Abstract
A snow chain for a motor vehicle tire which consists of a pair of side cables, a plurality of cross cables between the pair of side cables and connected to the side cables by connectors. Rotatably disposed grippers on the cross cables. Deformation of the connectors and damage to the tire is prevented by the insertion of a rubber ring on the cross cable between the grippers and the connector. One direction slippage (skid) is prevented by forming a space of "t" between axially disposed protrusions on the grippers disposed on the cross cables and means to join the ends of each of the side cables to one another.
