ABSTRACT:
A method to attach a cotter pin to a receptor at its through hole includes using a flat slider key whose aperture has surface zones against which the pin's legs bias into a conforming slidable fit. The key is initially remote from the legs' free ends and is oriented perpendicular to a plane defined by the legs. The key is slid along the legs, which are forced toward each other without eliminating the gap therebetween. The key is then pivoted until the legs close so as to fit their free ends into an entry of the receptor's hole. Once the legs' free ends are in the hole, the key is returned to its original orientation. The legs are then passed through the key further into the hole until their free ends exit the hole and spread apart more than hole's width.
