A coupling device (3), for coupling a load carrier (2) to a vehicle, preferably to the rear section (1) of the vehicle. The coupling device comprises a sleeve (4), which is mounted on the rear section (1), and a shaft (5), which is mounted on the load carrier (2), and the coupling is realized in that the shaft (5) is mounted into the sleeve (4), whereupon the shaft (5) is secured to the sleeve by means of a securing device (6), which is arranged on the shaft (5) wherein the securing device (6) comprises a lever link (10) that is, at a first end (11), pivotably arranged on the shaft (5) at its first end (8) by means of a pivot axes (12), which first end (8) is mounted to the sleeve (4) and, at a second end (13), in connection by means of a tension mechanism (14) with the shaft (5). The lever link (10) can be pivoted by the tension mechanism in a direction (P) away from the shaft (5), whereupon the lever link (10) and the shaft (5) are brought into secure clamping engagement with the inner walls (25) of the sleeve (4) when the shaft (5) is mounted to the sleeve (4).
