ABSTRACT:
A display accessory for rigid connection to a display panel of the type having an elongated longitudinal undercut retaining channel along one edge and having a narrow slot entrance to the retainer channel. The accessory includes a longitudinal tubular member of circular or polygonal cross-section and at least one pair of aligned longitudinally spaced apart connectors on the tubular member. Each of the connectors comprises a lock pin extending through the wall of the tubular member and having a large retaining head within the tubular member. The opposite end of the lock pin has a locking member having opposed flat faces. The shape of the locking member corresponds to the cross-section of the retainer channel of the panel to which the accessory is to be connected and the thickness of the locking member is such that it fits within the channel slot of the display panel. The lock pin extends through and is fixed to a manually operable rotator positioned between the outer wall of the tubular member and the locking member. Rotation of the rotator permits the accessory to be connected to and rigidly secured to a display panel.
