Abstract

An anti-skid device has rotating chains which are connected to an inner and an outer fixing device. The outer fixing device is formed from a ring-shaped disc (10) and a retainer ring (11). The retainer ring is provided for the end of a tensioning chain (8) which serves to lock or tension the inner fixing device formed by a spring steel clip. The disc (10) and the retainer ring (11) are detachably connected to each other for enabling the rotating chains (3, 4, 5, 6, 7) of the anti-skid device to turn.
