Abstract
A latch assembly includes a hook having an opening engageable to a keeper. A side plate having a straight slot and an angle slot is mounted to the hook via posts. A spring is provided to bias the plate so that it partially overlaps the opening. The plate prevents a latch handle from being moved into its closed position unless the hook is fully engaged onto a keeper.
