Abstract An add-on guard piece for the slider of a zipper slide fastener configured to minimize the tendency for jamming with fabric, the guard piece generally crescent shaped and attached to the forward end of the slider by a spring clip having a loop portion received around the slider post and legs snap fit into a cavity in the guard piece. A close fit of entryway openings in the guard piece to the zipper clasp elements, and sloping diverter surfaces act to reduce the tendency for jamming with adjacent fabric.
