The coupling consists of two flat plates (1, 2), one connected to the end of the manipulator arm and the other to the implement. The plates are joined at one end by a pivot (30) between two lugs (3) on one plate, connecting with a hook on the other, and locked by means of a sliding key (4) on one plate which engages with slots (23) in retaining elements (21) on the other. Each retaining element is basically cylindrical in shape and has a lateral slot to receive an edge (40) of the key (4), which is actuated by one or more power cylinders (13) and a T-shaped flat return spring (50).
