description A mechanism for coupling a semi-trailer to a tractor comprises a fifth wheel mechanism mounted on the tractor and king pin means mounted on the semi-trailer, which mechanism and which means are arranged, after having been brought into coupling position, to be locked in said position by means of a locking device which is operated by fluid pressure. Tracing of the coupling position between the fifth wheel mechanism and the king pin means is facilitated by means of a device which serves to raise and lower the fifth wheel mechanism and which is of the type that can be used to advantage as a spring for the spring suspension of the front end of the semi-trailer during driving.
