    Abstract: A vehicle is provided with a clamping profile which is secured along a wall of the vehicle for clamping advertising material to the vehicle, wherein the clamping profile is provided with a flexible lip which connects under pre-tension to the wall of the vehicle. Advertising material in the form of a sheet can be secured and/or replaced quickly and easily on such a vehicle. The flexible lip of the clamping profile counteracts the unsightly accumulation of dirt, prevents the securing of the profile on the surface from being affected and the profile cannot be caught in the wind.
