A snow chain (2) comprises an inner ring (3) and a series of portions of anti-skid chain (10,10'), disposed on the tread of the tyre (1) of the wheel, wherein at least some of said portions form the join between the outer ring and the inner ring (3). The portions of chain (10,10') are chains with twisted links, connected to each other by means of joining elements (4) comprising twisted triangular links consisting of three apexes (40) defining three substantially equal sides, in which each side comprises with respect to the resting surface of the tyre, a concave portion (41), a convex portion (42) and a central union portion (43) between the concave portion and the convex portion. Each apex (40) is defined between the concave portion (41) of one side and the convex portion (42) of the other side, so as to define a loop (45) facing towards the centre of the triangle and designed to receive the respective loop of a twisted terminal link (11) of said portions of chain (10,10') with twisted links. |
