Abstract
The disclosure concerns a buckle or latch for maintaining a lid in place on a container, such as a vacuum cleaner tank. The buckle includes a mounting bracket attached to the container. The bracket has a slot spaced down from the lid for receiving a hinge pin. The buckle includes a buckle element with a lower end having a hinge pin thereon which is swivelably held in the slot in the bracket. The buckle element has a hook at its upper end to snap over a detent on the edge flange of the lid. An upwardly facing abutment on the swiveling buckle element and located between the hinge pin and the hook is arranged so that it will engage a downwardly facing abutment on the mounting bracket when the buckle is closed. Upon attempted separation of the lid and container while the buckle is in place, any forces on the buckle are transmitted to the abutment of the buckle and then to the abutment on the mounting bracket and not to the hinge pin.
