Abstract: A corner protector has a pair of opposite frame embracing faces which are resilient and bowed so that, in use, the corner region of a frame to be protected must force its way into position on between the opposite faces of the protector and will thereafter be frictionally gripped between them until the protector is subsequently released by pulling it off against the frictional resistance. Frame-gripping ribs may be incorporated on the major faces of the protector and in addition the protector may be tapered outwardly from its apex to its open mouth to provide a lead for insertion of the frame. To provide a still greater lead, the open edges of the protector may each be given a slight flange extension, but at opposite ends of the two edges.
