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 spanning between an open first end and a closed second end. The main body portion has an outer surface defining the periphery of the cap member and an inner surface defining a nozzle receiving recess. A lock member having a arcuately shaped central portion terminating in opposed outwardly projecting first and second end tabs having a key-receiving gap therebetween is retained within an annular slot within the nozzle receiving recess. The lock member is resiliently deformable between a first locking configuration whereat, the central portion of the lock member is shaped and dimensioned to fit around a substantial portion of the gas outlet nozzle so as to be in interfering relation with a juxtaposed one of the serrations to thereby cause the cap member to be locked on the gas outlet nozzle, and a second unlocking configuration whereat, the central portion of the lock member is shaped and dimensioned to be removable over the serrations of the gas outlet nozzle so as to thereby permit the cap member to be removed from the gas outlet nozzle. An access passageway in the main body portion permits the key member to be inserted into the gap between the first and second end tabs so as to urge the lock member from its first locking configuration to its second unlocking configuration.
