Towing system with elongated shaft

A drawbar for connecting wheeled containers has a simple design using a flat bar (1) with lipped edges (40, 41) for strength. The drawbar is hinged on one container via a transverse horizontal axis (18) and is spring loaded to swing up into a vertical position flat against the side of the container. The free end of the drawbar is fitted with a loop (2) which is hooked over a downwards mounted coupling stub in a recess in the side of a similar container. The coupling stub has a retaining profile with a diameter smaller than the coupling ring. The drawbar is held on the coupling stub via spring pressure.
