Garment zippers incorporate spring latches to stay closed securely

Pull tab locking pins prevent clothing zips from sliding down under stress

Quality garment zippers incorporate an automatic locking mechanism inside the sliding pull tab. A small metal pin or spring catch engages between zipper teeth when the pull tab lies flat against the fabric tape. Lifting the tab releases the pin, permitting smooth sliding without unzipping under tension.
