Coupling device ( 4 ) for connecting a load carrier bar ( 3 ) extending laterally across a vehicle roof to a roof rail ( 2 ), which rail extends in the longitudinal direction (L) of the incorporating vehicle. The coupling device includes a base part ( 6 ) which, when the coupling device is connected to the roof rail, is securely attached to the load carrier bar, and which base part is provided with a contact surface ( 8 ) which is positioned on the roof rail, as well as a tightening arrangement ( 17, 23, 26, 27 ) connected to the base part and comprising a tightening strap ( 27 ) and a tightening device ( 23 ), the tightening strap enclosing the roof rail and being tightened by the tightening device, and n this manner a contact area ( 30 ) on the contact surface ( 8 ) is pressed against the roof rail, thus achieving secure connection of the coupling device to the roof rail, the base part ( 6 ) being of a convex arched shape ( 31 ) in the area to the front of the contact area ( 30 ), with respect to the longitudinal direction of the vehicle, when the contact surface ( 8 ) is tightened against the roof rail, and that the side of the arched shape facing the roof rail ( 2 ) is made of a ductile material.
