ABSTRACT:
A pull tab pivotally connected to a slider body is formed integral with a pair of locking cams which, when the pull tab is turned to a recumbent position on the slider body, intrude into the guide channel therein for pressing at least one fastener element into a depression formed in the inside surface of the bottom wing of the slider body and hence for locking the slider against movement. The depression is bounded at its front end by a pair of forwardly converging walls each formed at right angles with the plane of the slider body bottom wing and by a pair of rearwardly converging walls disposed between the forwardly converging walls and each inclined forwardly with respect to the plane of the slider body bottom wing.
