The clip-mount operates with a button sub-mount system and includes a body defining a locking cavity for the button and a resilient locking tongue therein. The tongue biases the button into a locking position with a cam surface. A movable cam actuator on the body includes another cam surface which coacts with the first cam permitting the tongue to flex or unlock. An enhancement includes both an unlocking cam and a second locking cam structure. The method includes biasing the button to a locking position and moving one cam over another thereby flexing the tongue from a locked to a button release position. The actuator maybe biased outboard or upward via a plastic spring on the actuator-plunger. A plastic leaf spring may be provided between a clip arm and the button clip mount body. A lock or latch may lock on the actuator-plunger.
