ABSTRACT:
A slider for a slide fastener is assembled essentially with a slider body, a pull tab, a cap-like yoke and means for locking the slider against movement along a pair of rows of fastener elements. The slider body has an upper shield with a pair of first engaging means provided at its front and rear ends, respectively. The upper shield has a plurality of longitudinally extending grooves formed therein. The yoke has a pair of second engaging means at its front and rear end walls and has separated longitudinal bottom edges. The first engaging means interengage with the second engaging means and the lower edges of the yoke are fitted in the groove in the upper shield. The yoke has a projecting surface disposed for engagement with a concaved surface of the upper shield, both surfaces being fused together by ultrasonic welding to provide a rugged slider construction.
