A traction device attachable to a tire mounted on a tire rim, the tire defining a pair of substantially annular and substantially opposed tire side walls, the tire also defining a tire thread extending between the tire side side walls, the traction device comprising: a first jaw, the first jaw defining a first jaw free end, the first jaw including a first tire gripping element provided substantially adjacent to the first jaw free end; a second jaw, the second jaw defining a second jaw free end, the second jaw including a second tire gripping element provided substantially adjacent to the second jaw free end; the first and second jaws being operatively coupled to each other so as to be movable between an open configuration and a closed configuration, the first and second tire gripping elements being closer to each other when the first and second jaws are in th e closed configuration than when the first and second jaws are in the open configuration; the traction device further comprising a traction element extending between the first and second jaws substantially opposed to the first and second jaw free ends; wherein, when the traction device is operatively mounted to t he tire with the first and second jaws in the closed configuration, the traction element extends across the tire thread and the first and second tire gripping elemen ts grip a respective one of the tire side walls so as to pinch the tire between the first and second tire gripping elements.
