A description is given of a towbar (1) composed of a straight part (11) terminating at its ends in two devices (2, 3) for hitching it to part of the structure of a motor vehicle, in which towbar the said straight part (11) consists of a plurality of coaxially aligned telescopic tubular segments (4, 5, 6), of which at least two consecutive segments (5, 6) are capable of sliding coaxially one inside the other, and between these (5, 6) is an elastic element (7) capable of damping the axial stresses to which the towbar (1) is subject when towing a motor vehicle.
