Abstract
A hinge includes a first leaf member with a pair of knuckles receiving a hinge pin therethrough. The knuckles include a retainer member which extends into the path of the pin. Annular grooves formed in the pin receive the retainer member to keep the pin from easily sliding in and out of the hinge. One of the grooves includes a straight side and a tapered side while the second groove includes a pair of tapered sides for allowing the retainer member to slide over the second groove but not over the first groove. In this manner, the pin may not be forced beyond the retainer member and is held in place even when pulled out of the first knuckle for removing secondly.
