A zipper with improved fastening stability is disclosed. The improved zipper opens and closes according to the engagement and separation of a plurality of coupling elements formed on facing surfaces of a pair of zipper tapes and includes a zipper slider for engaging and separating the coupling elements, guiding rails attached on upper surfaces of the zipper tapes, and an auxiliary slider that guides the guiding rails as they slide through it to thereby gather the zipper tapes before the coupling elements are engaged. The structure is compact, and the zipper can be engaged with minimal force, even when the garment is tightly stretched or the zippered enclosure (suitcase, e.g.) is tightly packed with material.
