Claim:
1. A mechanical coupling device, comprising: a square tubular structure arranged horizontally and provided with fastening through-holes ends next to fitting structures, the fitting structures including fastening through-holes and spacers; a “T”-shaped structure centrally located on the square tubular structure, the “T”-shaped structure having an “L” spacer in a rear portion, the “T”-shaped structure having in a front portion an end cap receiving projection, the end cap receiving projection including a circular spacer that defines an opening of an aperture having locking inner radial projections and a locking through-hole for receiving an anti-theft system; an end cap having a front end and a rear end, wherein the front end includes a ball and the rear end includes a tubular structure provided with first and second grooves, the tubular structure projecting away from a square structure arranged in a central portion of the end cap, between the front end and the rear end; wherein the anti-theft system includes a lock core configured to be inserted into a cylindrical structure, wherein the cylindrical structure has a thread in a first end, and wherein the anti-theft system further includes a threaded pin configured to compress a conical spring when the lock core is driven, an end of the threaded pin having a hole for guiding a threaded and locked pin in an end of the lock core; wherein the end cap is configured to be rotatably attachable and detachable to the “T”-shaped structure via mating of the locking inner radial projections of the aperture with the first and second grooves of the tubular structure.
