ABSTRACT:
A change return protection device is disclosed which prevents thieves from stuffing flexible material into coin-operated machines' coin return chutes. The device seals off the change return's change return chute when the change return door is opened, and it prevents stuffing of the change return chute by also incorporating a blocking flap and a slot blocking plate around which the flexible material cannot be inserted. The slot blocking plate has a V-shaped notch itself having sharpened edges which further prevents stuffing. In a preferred embodiment the edges of the notch are formed from two crossed replaceable razor blades which are removably mounted in the device. The device is suitable for use in existing change return mechanisms.
