ABSTRACT:
A display frame for holding a flat member includes a holding frame portion having a separable frame portion separably secured thereto in a manner permitting separation only by an authorized person having a special tool. The holding frame portion includes a slideway for receiving peripheral portions of a flat member and has a slideway entrance normally closed by the separable frame portion. The separable frame portion is separably secured to the holding frame portion by separable joints, at least one of which includes a locking member completely concealed within the frame and having a movable latch portion yieldably urged to a locked position, and being movable to a released position. A limited access opening through the frame near the locking member provides access to its latch portion with a special tool for moving same to its released position. Separation of the separable frame portion from the holding frame portion opens the slideway entrance and allows removal of the flat member from the slideway in the holding frame portion.
