The invention relates to a device for the detachable fitting of a traction aid (1) to at least two fixing devices (11, 12), applied to the inner circumferential surface (7) of the rim (2), in the vicinity of the rim edge, arranged opposing each other, essentially vertically on the plane of the rim and aligned with each other to form a pair. The first fixing device (11) thereof, facing the wheel inner side (7), with a first fixing element (13), serves for the hooking and unhooking of a second fixing element (15), complementary to said first fixing element (13), mounted on one end (14) of the traction aid (1), whilst the second fixing device (12), facing the wheel outer side (A), is provided with a second fixing element in the form of a coupling device (16), for the coupling and tensioning of a tension element (18), mounted on the other end (17) of the traction aid (1), such that the traction aid (1) may be tensioned transversely across the tyre (3) on the running surface (4), between both fixing devices (11, 12).
