• a latch member carried by said box and moveable between a first position capturing said retainer member and a second position releasing said retainer member;
• latch actuation means including an actuation member and a ball member received in an actuation cavity to operatively interconnect said actuation member and said latch member;
• labyrinth means received within said box and accessible only through said opening including a plurality of ball receiving channels formed by at least one chamber subdivided by a plurality of transverse partitions having ball passing apertures at diverse locations to define a continuous, three dimensional torturous passageway having cross passageways at mutually perpendicular orientations with at least one of said transverse partitions being removeably received in said chamber thereby permitting fixed adjustability of said latch enabling combinations;
• and
• a ball shunting passageway interconnecting intermediate locations of said torturous passageway with ball deflecting means interconnected to said actuation means and moveable therewith into a position permitting access to said shunting passageway.
