The rod (1) has a longitudinal flat (2), while the head (3) of the rod is provided at the top with a groove (4) in which the ring (5) is housed and retained. The ring (5) is open and the ends thereof are superimposed to permit the manual opening thereof, so that once the hitch pin is mounted, the ring (5) can be moved to the other part or face of the rod (1). <IMAGE></p> |
