Patent abstract

A locking assembly has two members which are moveable into coupling engagement with one another. The two members have lock engaging walls, and one of the members has an opening between the lock engaging walls for receiving a lock. The lock comprises a lock body and a retainer. The lock body has a channel for receiving a portion of the retainer. An end of the retainer extends underneath a retainer engaging wall, thus resisting movement of the lock out of the opening.
