Abstract
The anti-skid device includes a housing capable of being removably fastened on an outer side of a vehicle wheel. An anti-skid travel path, formed of chains, is connected to a plurality of radial arms of the housing. The chains are automatically positioned on the wheel of the vehicle upon advancement of the vehicle, when an elastic member extending through the housing pulls the housing in a direction towards the wheel. A lever is provided between the housing and the wheel and includes an extension which extends through a radial passage of a fastening device connected to a nut of the wheel.
