Abstract: A protective cover for the coinbox-containing portion of pay telephones of generally box-like construction, comprises a front panel flanked by a pair of parallel, rearwardly-extending side walls to define a generally U-shaped construction. The construction closely abuts the front and side panels of the telephone. The front panel is adapted to be permanently fastened to the coinbox cover of the telephone, such as by welding, and has an entryway to the telephone coin return slot and an integral raised portion positioned to overlie the top portion of the coin return door plate of the telephone.
