To provide a snow chain with a limited bulk on both sides of a tire, in particular, when the snow chains are mounted on the tire so that a mechanism part of a vehicle is not interfered with the snow chain.

A snow chain comprises an inner ring (3) designed to be closed on the side of the wheel destined to face toward the inside of a vehicle, an outer ring designed to be closed on the opposite side of the wheel destined to face toward the outside of the vehicle and a series of portions of anti-skid chains 10, 10' disposed on the tread of the tire (1) of the wheel, which join the outer ring with the inner ring (3). The chain (10) consists of chain links of a twisted shape, and the chains are connected with each other by means of joining elements (4) shaped as triangular links, and connected to the inner ring (3) by means of a U-bolt connecting system.
