Zusammenfassung:	A vacuum-operated brake booster includes a housing which consists of a bottom and a cover having an intermediate piston through which tubes, through which attachment screws are to pass, extend. The front end of the tube is threaded, and a peripheral groove is provided behind the thread, a flange being crimped in the groove behind the cover in the housing. The master cylinder is attached via the lugs thereof, which are fitted into the front end of the tube against the front surface of the cover and locked by the nut screwed onto the thread. The front end of the tube has a peripheral groove receiving the flange that consists of a ring and a sleeve, the lip of which penetrates into the groove by crimping. A gasket completes the seal.
