Abstract
A slide fastener has a pair of longitudinally extending and parallel textile tapes having thickened longitudinal edges that are transversely juxtaposed and formed with throughgoing holes at transversely aligned locations and that are provided with respective longitudinally extending rows of transversely projecting and interleavable coupling teeth. A slider having slots fittable over the edges is displaceable along the edges over the teeth in one longitudinal direction for interleaving the teeth and coupling the tapes together transversely and in the opposite direction for disengaging the teeth from each other and decoupling the tapes from each other. Thickened synthetic-resin reinforcement tabs are integrally molded onto the tapes at the locations of the throughgoing holes and extend thereat transversely up to the edges. Synthetic-resin coupling lugs molded on the edges at the locations each have a pair of ribs flanking the respective tape at the respective holes and unitarily joined with each other through the tape at the holes. The lugs and their ribs are engageable through the respective slots of the slider.
