Abstract
Abstract A horseshoe shaped body formed of planar sheet metal is formed with a pair of legs joined at one end by an arcuate web. A portion of the web is bent perpendicularly to the legs, and each of said legs has a flange extending outwardly within the plane of the body at each of its free ends. A series of teeth along the inner edges thereof receive and mesh with the threads of the screw inserted therebetween.
