A zipper is a common fastening device consisting of two flexible strips of material with teeth that interlock. When the slider is pulled, the teeth engage and the zipper closes. However, zippers can sometimes become separated, which can be frustrating and inconvenient.
There are a few different ways to repair a separated zipper, depending on the type of zipper and the severity of the damage. In many cases, a simple solution like using a pair of pliers to re-align the teeth will suffice. For more severe damage, it may be necessary to replace the slider or even the entire zipper.
