Support member with variable position on tubular uprights. This member comprises a rectilinear portion 2 and a cylindrical helical portion 3, the latter being composed of two coil segments, 3a, 3b surrounding an upright 4 and spaced apart sufficiently so that the member can be positioned directly on this upright at any point when access to one end is not possible, the portion 2 serving to support or carry any object. <IMAGE> |
