This invention relates to a continuous snow chain comprising three cords or chains disposed in zig-zag patterns and connected to each other in a network of cords or chains of a finite length including two parallel rows of substantially diamond-shaped openings. One cord or chain constituting one boundary of the network of cords or chains is slidably connected to a first retaining cord at each of the zig-zag points constituting the one boundary of the network of cords or chains, which first retaining cord includes means for connecting two extremities thereof to one another. The other cord or chain constituting the other boundary of the network of cords or chains is slidably connected to a second retaining cord at each of the zig-zag points constituting the other boundary of the network of cords or chains, which second retaining cord includes means for connecting two extremities thereof to one another. A segment of a cord or chain connected to one extremity of the second retaining cord and extending therefrom converts the open segment of the network of cords or chains into a closed loop when the segment of a cord or chain is routed through the diamond-shaped openings disposed at two extremities of the network of cords or chains in a zig-zag pattern across the network of cords or chains and the extremity thereof is connected to the connection between two extremities of the first retaining cord.
