Title: Hinge assembly having an L-shaped locking tab

Abstract: A hinge assembly includes a hinge pin which passes through interfitting knuckles of two leaves which are to be hinged. An L-shaped tab lock has, in one embodiment, one leg trapped between a pair of the knuckles and another leg which passes through a slot in the head of the hinge pin and is folded over to prevent axial movement of the pin relative to the tab lock and knuckles. Preferably a flat on the side of the pin head abuts a flat surface on one of the leaves to prevent movement of the pin relative to that leaf.
