A sliding clasp fastener or zipper has an automatic bottom stop consisting of three parts: a male member and a female member which are secured to the opposite halves of the zipper after their last teeth and which are shaped for coupling engagement by rotating one towards the other, and a stopper element of parallelipipedic shape secured to either zipper half beneath the corresponding one of said members in such manner that its oblique sides lie substantially at right angles to the general plane of the zipper. One of the lower transverse edges of the stopper element is bevelled. |
