Patent ID: 6874338

Claim:
A locking device, comprising: an elongate, rigid hollow sleeve collectively formed by a first sleeve part and a second sleeve part that confront one another along a top parting line and a bottom parting line when said rigid hollow sleeve is in a closed configuration; an elongate hinge means for hingedly interconnecting said first sleeve part and said second sleeve part to one another along said bottom parting line; said elongate hinge means including an elongate hinge post; said first and second sleeve part abuttingly engaging one another along said top parting line when said rigid hollow sleeve is in said closed configuration; a first locking means that secures together said first and second sleeve parts along said top parting line when said rind hollow sleeve is in said closed configuration; and a second locking means that prevents hinged motion between said first and second sleeve parts along said bottom parting line when said rigid hollow sleeve is in said closed configuration; said second locking means including a first bottom lock lug formed integrally with said first sleeve and a second bottom lock lug formed integrally with said second sleeve; a first transversely extending slot formed in said second sleeve to accommodate said first bottom lock lug when said rigid hollow sleeve is in an open configuration; and a second transversely extending slot formed in said first sleeve to accommodate said second bottom lock lug when said rigid hollow sleeve is in said open configuration; whereby said second locking means prevents hinged motion between said first and second parts when said rigid hollow sleeve is in said closed configuration even if said first locking means is rendered non-functional.
