Abstract
A plastic over-center hollow wall anchor having increased strength without increase in thickness of load bearing members and necessitation of a larger insertion aperture. The bending motion stress on the load bearing arms, which causes the weakening or failure mode of the anchor, is substantially retarded by the inclusion of a small reinforcing boss across the bending area.
