ABSTRACT:
Heavy-duty cotter pin for retaining retainer member in position. The legs of the cotter pin each have an integrally formed locking arm extending angularly outwardly therefrom, locking the cotter pin in position without forcefully spreading or deforming the legs. The legs of the cotter pin are biased outwardly relative to each other and extend from a bight portion of the pin at equal angles with respect to the longitudinal center line of the pin. The legs are moved toward and laterally of each other to enter the hole of a pin or other retainer member and clear the locking arms from the hole. The locking arms are maintained in their angular outwardly extending position, both during placing of the cotter pin in a hole and removing the cotter pin from the hole. The pin cannot be released except by flexing the legs toward each other against their spring bias and then moving them laterally in opposite directions to clear the locking arms from the internal periphery of the hole and to accommodate ready removal thereof, without deforming the legs.
