How to Replace a Broken Zipper Pull on a Sewn Garment or Bag

Quick answer

You can replace a broken zipper pull without unpicking the whole zipper. If the zipper teeth are intact and the slider still closes them, clip a replacement tirette onto the existing slider. If the slider itself is loose or no longer joins the teeth, replace the slider and pull together. Work on a flat surface, match the pull size to your zipper, and test the zipper before you wear or use the item.

A zipper pull snaps, the tab breaks off, and suddenly a perfectly good jacket or bag feels unusable. The good news is that the zipper tape and teeth are usually fine. Most of the time only the pull, or the slider and pull together, need attention.

This guide walks through the repair in order, from checking whether the slider is still usable to clipping on a replacement pull and testing the result. It applies to garments, pouches, and bags, and it uses a replacement tirette that snaps onto the slider without sewing.

Before you start: check what actually broke

Zip the item closed and look closely at the slider. If the teeth meet and stay closed behind the slider, the slider is probably still good and you only need a new pull. If the teeth separate behind the slider, or the slider slides freely without closing them, the slider is worn and should be replaced too.

Also check the zipper tape for tears, missing teeth, or a stop that has come loose. A pull replacement will not fix damaged teeth or torn tape. In that case the repair is a sewing job, not a clip-on job, and it may be worth a tailor.

Measure the width of the slider where the pull attaches, and note the zipper size if you know it. Replacement pulls come in different sizes and colors, so matching the old one avoids a second order.

• Common mistake: ordering a pull before checking whether the slider still closes the teeth.
• Checkpoint: zip the item and watch the teeth behind the slider. Closed teeth mean a pull-only repair is possible.

Step 1: Open the zipper and secure the slider

Open the zipper about halfway so you have room to work and the slider is not under tension. If the old pull is still attached but broken, remove any sharp fragments so they do not catch on fabric.

Pin or clip the zipper tape just below the slider so it cannot slide down while you work. On a bag, empty the pocket first so small parts do not fall inside. Work over a tray or a light-colored cloth so a dropped pull is easy to find.

This is also the moment to clean the teeth with a soft brush. Grit and lint make a new pull feel stiff and can make you think the repair failed.

• Common mistake: working over a carpet, where a dropped pull disappears.
• Checkpoint: the slider should be reachable from both sides and the zipper should not be under tension.

Step 2: Remove the old pull or slider

If only the pull is broken, look at how it attaches to the slider. Many pulls clip into a small loop or hole on the slider. Use small pliers or your fingers to release the old pull, taking care not to bend the slider body.

If the slider must be replaced, remove the top stop or the stitching that holds the zipper end, then slide the old slider off the top. On some garments the top stop is a metal staple; on others it is a sewn bar. Do not cut the zipper tape itself.

Keep the old slider and pull together until the new one is fitted. They are a useful reference for size and orientation, and you can compare them side by side before committing.

• Common mistake: prying the slider open with a screwdriver, which ruins it for reuse.
• Checkpoint: if the top stop cannot be removed without damaging the garment, stop and consider a tailor.

Step 3: Fit the replacement pull or slider

For a clip-on replacement pull, align the new pull with the attachment point on the slider and press or clip it into place until it seats. It should hang freely and pivot without binding. If it feels tight, check that it is fully seated rather than forcing it.

For a full slider replacement, slide the new slider onto the zipper tape from the top, making sure both sides of the tape enter the correct channels. This is the step where most repairs go wrong: a slider installed upside down or with one tape outside the channel will never close the teeth.

Once the slider is on, refit or replace the top stop. If you removed stitching, re-sew it with a matching thread and a few backstitches for strength.

• Common mistake: installing the slider upside down, which makes the pull hang the wrong way.
• Checkpoint: pull the slider down a few centimeters. Both tapes should feed evenly and the teeth should meet.

Step 4: Test, adjust, and finish

Zip the item fully closed, then open it again. Do this several times. The action should feel smooth, and the teeth should stay closed behind the slider. If the slider jumps or the teeth separate, stop and recheck the installation before using the item.

If the pull hangs awkwardly or rubs, a small pair of sharp snips can trim a stray thread near the attachment point. Do not trim the zipper tape. For bags that carry weight, give the zipper a firm tug with the bag partly loaded to confirm it holds.

Finally, note the size and color of the pull you used. If the same zipper fails later, you already know what to order.

• Common mistake: testing only once and assuming the repair is done.
• Checkpoint: five smooth open-and-close cycles with no separated teeth means the repair is reliable.

The repair sequence at a glance

1. Diagnose the failure: Zip the item and watch the teeth behind the slider. Closed teeth mean the slider is fine and only the pull needs replacing. Checkpoint: if the teeth separate, plan for a slider replacement, not just a pull.
2. Open and secure: Open the zipper halfway, pin the tape below the slider, and work over a tray so small parts stay findable. Checkpoint: the slider should be accessible and free of tension.
3. Remove the old part: Release the broken pull from the slider, or slide the slider off the top after removing the top stop. Checkpoint: keep the old parts as a size reference.
4. Install the replacement: Clip the new pull onto the slider, or feed both tapes into the new slider from the top with the correct orientation. Checkpoint: the pull should pivot freely and the teeth should meet when zipped.
5. Test and finish: Cycle the zipper five times, trim stray threads, and confirm the zipper holds under a light load. Checkpoint: any jumping or separation means recheck the installation before use.

Parts that make this repair easier

• Tirette de rechange pour fermeture éclair: Replacement zipper pull available in 2 sizes and 3 colors; it clips onto the slider to restore function without replacing the whole zipper. This is the part that turns a broken pull into a two-minute fix. Matching size and color keeps the repair looking intentional.
• Ciseaux de broderie - Collection Marée haute: Small 10 cm snips with a 2 cm blade, suited to precise thread cutting and beginner use. Their small size lets you trim loose threads near the slider without cutting the zipper tape or the fabric.
• Ciseaux tailleur professionnels: Bent professional dressmaking shears designed for intensive sewing and thick fabrics, in a range of sizes. If the repair turns into replacing the zipper tape, these shears cut fabric and heavy layers cleanly instead of chewing the edge.

A broken zipper pull is one of the quickest clothing and bag repairs you can do yourself. Check the slider first, match the replacement pull to your zipper, and test the zipper before you rely on it again. With the right tirette on hand, the fix takes minutes and saves the item.
