Abstract

A tensioning device for a tire chain, which comprises a first link member adapted to receive a chain link, a second link member adapted to receive another chain link, and an intermediate member, e.g. in the form of a tubular member, which is connected to the first link member and is interposed between the first link member and the second link member. The second link member is movable relative to the intermediate member. A shaft member which is associated with the intermediate member is fixedly connected to the second link member while being movable relative to the first link member. Preloaded springs are associated with the intermediate member and continuously act upon the connecting member so as to urge the second link member in the direction toward the first link member.
