Abstract
Anti-skid tire chains for automobiles are known to be consisted of a various number of cross strands of steel or plastic link chains which have been fitted together into a harness or halter type of arrangement, and which is affixed to an automobile tire by means of some type of fastener mechanism which has been engineered (in peculiarity) to a given make of tire chain. In this invention, only one strand of steel or plastic link chain is constituted in every complete unit. Independent strips of flexible moulded plastic, having serrations molded onto one of the surfaces of each, are fitted to each end of the chain, and in their function thereof comprise a graduated fastener. A further independent piece of hard plastic, moulded in a `C`-clasp type configuration, serves to lock the fastener parts together. The invention is affixed to the tire through a wheel fello, and when installed, the whole has assumed the shape of a loop enclosing the `tubularity` of the tire.
