ABSTRACT:
A lock for a retainer pin prevents accidental opening of the ring of the retainer pin. A body has an elongated slot receiving the ring of a retainer pin, with a detent to inhibit motion of the body on the ring. A bore in the body is alignable with the pin of the retainer pin. The bore has an open portion that allows free movement away from the pin, and a closed portion that prevents movement away from the pin. The retainer pin may have a colored portion that is outside the bore when the pin is received only in the open portion of the bore, and is inside the bore when the pin is received in the closed portion of the bore.
