• wherein the locking tongues are integrally formed with said locking plate and coplanar with said locking plate;
• a plurality of receptacles formed in the display rod and being configured for coupling to a mounting anchor of a frame holder;
• a key and a linkage pin;
• a cam lock rotatably disposed in the display rod, the cam lock including an operating cylinder which receives the key and the linkage pin;
• the linkage pin being movably coupled to the locking plate;
• wherein the cam lock is operable to move the locking tongues between a locked position in which the tongues move downward to substantially block corresponding receptacles wherein the tongues intersect a central axis of a corresponding receptacle and an unlocked position in which the tongues move upward to substantially unblock corresponding receptacles wherein the tongues do not intersect a central axis of a corresponding receptacle by rotating the operating cylinder with the key.
