A device has a detachably fitting traction aid to be attached using at least two fixing devices, applied to the inner circumferential surface of a rim, in the vicinity of the rim edge, disposed opposing each other, substantially vertically on the plane of the rim and aligned with each other. A first fixing device, faces the wheel inner side, and has a first fixing element for the hooking and unhooking to a second fixing element, complementary to the first fixing element, mounted on one end of the traction aid. The second fixing device, faces the wheel outer side, and has a second fixing element being a coupling device, for coupling and tensioning a tension element, mounted on the other end of the traction aid, such that the traction aid may be tensioned transversely across the tire on the running surface, between both fixing devices.
