The coupling is formed from the use of two pieces which in general have the configuration of a parallelepipedal body in their mounting, having a suitably sized rear groove via which insertion of the plate joined to the chassis in a removable manner is obtained, having a complementary piece of cylindrical configuration which carries bolts at its end joined with a chain, which produces actual joining between both pieces upon passing through holes located in the sides of the two pieces, a piece which has the configuration of an inverted L being joined to the assembly by suitable screw fittings, the towing ball being located in the upper part of the aforesaid inverted L and there being holes which allow the passage of the connecting screws. <IMAGE>
