ABSTRACT:
An automatically locking slider for slide fasteners has a locking member including a piece of resilient strip, preferably made of stainless steel, which is bent into a generally "3" shape having a U-shaped base extending around a transverse spindle of a pull tab, a locking prong extending from one end of the base, and an anchor extending from the other end of the base and terminating in a hook-shaped end hooked with a locking-member retaining nose on a slider's neck. The base is normally urged against the spindle of the pull tab by the resilience of the strip. The hook-shaped end of the anchor is normally urged against the nose by the resilience of the strip and is thereby prevented from being unhooked from the nose. Thus the locking member is held in position on a slider body solely by the resilience of the strip, requiring no bending or deforming of any part of the slider body that would make the slider defective from an aesthetic view.
