Vehicles without their own brakes carry wheel chocks, which are releasably fixed in a holder which can be fastened on the vehicle. With an arrangement of this type it is possible to achieve high operational dependability and cost-effective availability by providing, in the area of the lateral edges of the bottom plate of the wheel chock and the lateral cheeks of the base plate of the holder, a holding device with coupling elements, which can be brought into mutual engagement, which are respectively embodied as insertion bolt and receiving pocket and can be brought into mutual engagement by means of an L-shaped movement with an insertion movement extending perpendicularly in respect to the base plate and a push movement extending in the longitudinal direction of the base plate, and that at least one spring arm projects backward from the base plate of the holder, which has at least one protrusion which reaches around the back edge of the wheel chock when the holding device is brought into engagement and can be taken out of engagement against the spring force of the spring arm.
