The free end of the vehicle support arm (2) includes a vehicle support plate that receives an edge of the bodywork of the vehicle, and the support leg has a swivel mounted support foot that rotates on an axis essentially parallel to the movement axis of the vehicle support arm. A bar (23) is fixed to the beginning of the vehicle support arm (2) and passes through the interior of the support leg (1) until it enters between the base of the end of the support leg (1) and the bottom of the foot (3), making contact with the foot.
