ABSTRACT:
A closure lock to discourage theft of fuel from tanks is disclosed. A lock body is threadedly engaged with a tank closure cap and contains a key-operated eccentric which is biased toward a grip or locking position with a cable extending through a passage in the lock body and being secured to a locking bar which bridges the lower end of a splash sleeve within the tank adjacent to the tank filling opening. Releasing of the cable allows the cable and locking bar to drop to a position within the tank whereby the tank closure cap can be removed.
