<p>The stop is for the slide of a slide clasp fastener, with two complementary shaped parts that clip together when the slide is pulled over them. The stop has two elements, one fixed to each band of the fastener, that clip tother. One element (5) has a split ball (5d) that fits into a hole in the other. The entrance of the hole is slightly narrower than the ball so the ball has to be pushed into the hole and can only be removed by a particular action of the user.</p> |
