Abstract: The invention relates to an anti-skid device for vehicle wheels, comprising a plurality of U-shaped elements radially mounted on the wheel tire, and two series of connecting levers pivoted on each arm of said U-shaped elements. In order to provide an automatic mounting operation of the device on a vehicle wheel by simply advancing the wheel on the device, each arm of each of the U-shaped elements carries retaining means for said levers, which removably retain the U-shaped elements and levers in a relative position wherein each of said U-shaped elements forms a pre-set angle with the levers adjacent to the same, said angle corresponding to that formed when the device is mounted on the tire.

Abstract: The invention relates to an anti-skid device for vehicle wheels, formed by a plurality of U-shaped elements adapted to radially fit on the wheel tire and rim, said elements being connected with one another by spacers allowing the device to be put flat on the ground and to be automatically mounted on the wheel by simply advancing said wheel on the device.
