The invention relates to a connection structure between a brake booster and a control valve which selectively introduces a negative pressure or an atmosphere into the booster. A brake booster of tandem type includes a front shell on which a pair of bosses are connected so as to extend parallel to each other. One end of one of the bosses is connected to a housing of the control valve while one end of the other boss is connected to the housing of the control valve through an L-shaped connection pipe. One end of the L-shaped connection pipe is rotatable with respect to one end of the other boss, and the other end of the L-shaped connection pipe is displaceable axially of the engaging opening in the housing during assembly. This construction allows the control valve to be assembled into the brake booster without requiring undue demand on the precision of the manufacturing various parts, while also minimizing the space required for the connection pipe.
