A retaining arrangement, including a support arm is proposed, by means of which an operating unit is connected with a vehicle. The retaining arrangement includes a safety device which operates such that, as long as a predetermined condition is not fulfilled, the connection of the operating unit with the vehicle is maintained. The operating unit is connected with the support arm in such a way that the operating unit can pivot with respect to the support arm about at least one axis provided with at least one vertical component that is arranged in a generally central region of the operating unit, when the safety device frees the connection.
