The present invention relates to a pneumatic brake force booster with means for fastening the said to a vehicle wall which extend through the interior of the brake force booster, wherein a fixed stop for a first housing part is provided on a first end and a stop that is adjustable by means of a rotation for a second housing part is provided on a second end, and with means for the pneumatic sealing of housing openings for the fastening means. The gist of the present invention resides in that the fastening means has a smooth sealing portion adjacent to the adjustment area of the adjustable stop, and in that the sealing means, by multilateral abutment on a conical abutment surface of the adjustable stop, on the smooth sealing portion and the associated housing portion, closes a slot between the fastening means and the adjustable stop and a slot between the stop and the housing part. This achieves a simple and low-cost sealing of housing openings for the fastening means.
