ABSTRACT:
An automatic lock slider for slide fasteners comprises a slider body including an upper and a lower wing defining therebetween a guide channel for the passage of slide fastener coupling elements, a locking member for locking the slider against movement, a pull tab operatively associated with the locking member for manipulating the slider, a casing and a spring member interposed between the casing and the locking member and normally urging the latter in a direction to lock the slider. The casing has retaining lugs interiorly disposed for folding over the spring member to retain the latter in position stably but loosely to permit its resilient movement relative to the locking member.
