ABSTRACT:
An end connector for double-pin track shoes or the like receives a pair of pins having arcuate grooves therein. The connector includes pin receiving openings having small diameter pin engaging arcuate surfaces, and large diameter arcuate grooves therebetween which nest arcuate portions of a spring therein. The spring also includes resiliently stressed portions that snap into the arcuate grooves in the pins when assembled, and a cap screw operatively connected between two walls of the connector clamps the connector onto the pins, thus providing double protection for maintaining the connector on the pins.
