The device includes a lock 20 mechanism with removable key, a helical turn screw and screw sleeve by which key rotation is translated into lineal movement, a cam-actuator affixed to the screw and which is moved by the turning of the key and cams 24 that are coupled to the actuator and which extend from the device or retract as a result of key rotation.
