A lockable closure for a gasoline filler tube is provided including a threaded extension which can be tightly threaded into the upper open end of a vehicle filler tube. The closure housing has an opening extending through the housing to communicate with the filler tube cavity as well as a flat upper surface of the housing which provides a sealing surface for a vapor boot during refueling. A locking plate assembly has a pair of spaced apart plates slidably received in the closure housing for movement into covering relation to the cavity or radially outwardly to an extended position leaving the housing cavity exposed for fuel entry. The closure may be locked in place.
