ABSTRACT:
An auto-lock slider, for a concealed slide fastener, comprises: a slider body having a guide lug having in its upper portion a locking-lever-receiving groove and a leaf-spring-receiving portion; a locking lever received in the locking-lever-receiving groove, the locking lever having at one end a locking claw and at the other end an anchor portion; a horizontal U-shape leaf spring covering the locking lever at a side toward the anchor portion in such a manner that the anchor portion is pivotably held within the groove and the locking claw is resiliently urged to project into a coupling-element-guide channel in the body. Since the number of components of the slider is small, the slider can be assembled simply.
