发明名称 Post and rail interconnection
摘要 A simple, yet secure connection between a vertical upright, such as a fence post, and a horizontal rail. The rail has secured thereto at either end, a collar of a material having memory and having a pair of spaced, vertically extending ears, with radially outwardly extending ends, adapted to pass through and expand against the internal surfaces of an outwardly extending, generally horizontal, closed loop. If necessary, a wedge or keeper may be driven between the ears once they are in place, thus preventing removal of the rail.
