The assembly means comprise a rod (21) extending along the cross-member and bearing, at a first (22) of its ends, an abutment head (24) which can abut one of the front and rear frame elements, as well as fixing means (27) and counter fixing means (28) formed on a second end (23) of the rod (21) and on the other of the front and rear frame elements, respectively, the fixing means and the counter fixing means being mutually engageable in order to move the front and rear frame elements towards and clamp them against the longitudinal ends of the cross-member as a result of a movement of the rod relative to the other of the front and rear elements.</p> |
