ABSTRACT:
An automatic lock slider for slide fastener comprises a slider body, a support lug integral with and disposed over the top surface of the slider body and a pull tab with which to move the slider. The slider includes a locking member in the form of a polygonal leaf spring having at one end a locking prong and at the other end a U-bent portion. A bulged portion is formed intermediate the prong and the U-bent portion and spaced a sufficient distance from the lower surface of the lug to permit lifting of the prong clear out of the passage of coupling element rows of a slide fastener.
