ABSTRACT:
A back clip comprising a clip body and a drive pin. A wall anchor is integral with the clip body and has fingers laterally expandable when the drive pin is driven through the anchor. The fingers have transverse wall portions engageable by the drive pin to swing the fingers to substantially ninety degree angles to the axis of the drive pin and anchor. A web is in front of the transverse wall portions in the path of the drive pin. A hook member on the body receives a shelf wire. A stop is hinged to the body by an integral short plastic strap and is pivotable to block the open side of the hook member and to hide the head of the drive pin.
