The free end of one of the sections remote from the other section includes first structure for articulated connection to a towing vehicle and the free end of the other section remote from the aforementioned one section includes second structure for stationary attachment to a towed vehicle. In addition, third structure is operatively connected between the arm sections to forcibly effect relative angular displacement of the arm sections to depress the free ends relative to the joined end portions. The first structure comprises a socket hitch member for removable coupling to a ball hitch member of a towing vehicle and the second structure includes a terminal end shank portion for removable anchoring in an endwise outwardly opening socket member mounted on the towed vehicle. Further, the third structure includes a hydraulic ram.
