ABSTRACT:
In an automatic lock slide fastener slider, a slider body has on the upper surface of an upper wing a pull-tab attaching lug at is front end, an auxiliary lug at its rear end, and a guide projection between the attaching lug and a locking-pawl-insertion though-hole. The attaching lug has a central groove, a pair of transverse recesses and opposite side recesses. The auxiliary lug has a vertical groove and opposite side recesses. The guide projection has a central cutout contiguous to the through-hole. A locking leaf spring has at one end a resilient portion to be received in the central groove and the other end a locking pawl to be inserted in the though-hole. With a pintle of a pull tab between the attaching lug and the guide projection, a cover is mounted over the two lugs so as to hold the resilient-portion-side end of the leaf spring.
