A low-pressure brake booster for automotive vehicles comprises a low-pressure casing sealingly subdivided into a low-pressure chamber and a working chamber by means of an axially movable wall. The axially movable wall is connected to an axially movable control valve housing of a control valve via a transmitting sleeve having longitudinal slots. The inside diameter of the transmitting sleeve exceeds the outside diameter of a reinforcement tube interconnecting the transverse end walls of the low-pressure casing. Arranged at the end of the reinforcement tube adjacent the working chamber are radial extensions which extend through the longitudinal slots of the transmitting sleeve and are connected to the adjacent transverse end wall of the low-pressure casing.
