ABSTRACT:
A cap member for fitment over a gas outlet nozzle having a plurality of serrations on the exterior thereof, is disclosed. The cap member comprises a peripherally disposed main body portion having an inner surface and an outer surface, the inner surface defining a nozzle receiving recess, an open first end, a generally closed second end, and a lock member. The lock member has a projecting lock portion movable between a first locking position and a second unlocking position. When the projecting lock portion is in the first locking position, the projecting lock portion projects into the nozzle receiving recess so as to be in interfering relation with one of the plurality of serrations on the exterior of the gas outlet nozzle, so as to thereby lock the cap member in place and preclude the cap member from being removed from the nozzle. When the projecting lock portion is in the second unlocking position, the projecting lock portion no longer projects into the nozzle receiving recess so as to no longer be in interfering relation with any of the plurality of serrations on the exterior of the gas outlet nozzle, so as to thereby permit the cap to be removed from the nozzle. The cap member further comprises an access passageway to permit access by a co-operating key member to the projecting lock portion of the lock member, to thereby allow the key member to contact and thereby move the projecting lock portion from its first locking position to its second unlocking position.
