ABSTRACT:
In a first embodiment thereof, the locking means comprises an axially-translatable bolt slidably disposed within a cylinder. The cylinder has an axially-extended slot formed therein, and a pin fixed in the bolt projects therefrom, through the slot, to engage a camming slot formed in a sleeve which envelops the cylinder. A hollow cap-actuator envelops the camming-slotted sleeve, and a drive rib formed in the cap-actuator engages an axial separation in the sleeve to cause (a) the sleeve to rotate, when the cap-actuator is turned, (b) to cause the pin to travel along the camming slot, and (c) to effect extension and retraction of the bolt.
