The fifth wheel 5 of the tractor of a tractor-trailer combination is provided with a kingpin opening 15 for receiving the kingpin 11, as well as an entry opening 17 connected to the kingpin opening 15 for guiding the kingpin to the kingpin opening during coupling. The fifth wheel 9 is provided with locking means for locking the kingpin 11 in the kingpin opening 15. The fifth wheel 5 is furthermore provided with a sensor which can determine the position of the kingpin 11 in the fifth wheel 5. The tractor has a control unit to which the sensor is connected. If, while driving, the control unit detects that the kingpin 11 has moved out of the kingpin opening 15, it activates the blocking means to prevent further movement of the kingpin in order to prevent the semi-trailer from becoming detached from the tractor. These blocking means have a blocking element 23 which can block the entry opening 17.
