A traction device having a pair of cleats that mount on the periphery of an automobile tire to provide temporary traction on ice, deep snow, mud and other adverse conditions for on and off the road travel. The cleats are each rigidly mounted to a pair of channels with one of the channels being inserted into the other to allow mounting of the cleats on a wheel. A handle mounted by a linkage to one of the channels engages protruding latches on the other channel, such that rotation of the handle draws the two channels together until the handle reaches a locked position wherein the cleats are firmly held on the tire.
