Abstract: A skid-resisting chain adapted to be attached to and removed from the tires of a vehicle with a minimum of effort to provide improved traction in snow, ice, mud or other slippery road conditions. The attachment-detachment means comprises a flexible metal cable adapted to tie the tire chain around the tire and wheel and a biased cam gripping means adapted to frictionally-engage the end of the cable in a manner which provides increased locking action when a withdrawal force is applied to the cable and yet permits easy release when a tightening force or a detachment force is applied to the cable.
