A protective chain for an automotive tire consists of a reticulation of elongate, end-perforated links, and connectors on to which the links are threaded, usually four to a connector, the connectors having open gaps to allow the threading of the links, and being shaped for the links to be threadable on to and separable from them only by relative rotational movement of the connector and link. The connectors are preferably omega-shaped or gammadions.
