Control unit for vehicles

The device has a board (4) and at least two gripping elements holding it between them, each with a fitting region (7) retaining the board and a base part (6) carrying the fitting region. At least one gripping element is an elastic latching hook (5) with its fitting region on the side of its base part away from the other gripping element. Exerting force on the board towards the fitting region of this hook moves it towards the gripping element.
