A replacement zipper pull is a device used to replace a broken zipper pull. The zipper pull is the part of the zipper that is pulled to slide the slider up and down in order to open or close it.
Commercial replacement zipper pulls usually consist of a cord that is threaded through the hole in the zipper slider to attach the pull. The rest of the pull consists of any type of material that is easy to grasp, so that the slider can be pulled up and down. Homemade replacement zipper pulls can be made out of things such as a paperclip or a key ring.
