Improvements in the construction of slide fasteners, consisting in that each of the two halves that make up the zip fastener comprises a belt, thin and thin fabric, doubly folded longitudinally so that the two strips of the same edge cover the central area, said central zone being also folded longitudinally together with at least one of the previous strips to form a bead inside which a longitudinal reinforcing element is arranged, and the teeth being held together in the reinforced bead formed thereby they constitute the zipper, in such a way that its jaws imprison the tape by a narrow longitudinal strip adjoining said bead and formed by at least three superimposed layers of fabric.
