Abstract: The invention concerns a device for coupling a vacuum pump (3) with a camshaft (1) of a motor vehicle internal combustion engine, comprising an end piece (6) provided with first and second coaxial portions (7, 9) delimiting an annular space wherein is mounted one of the ends of the camshaft, at least one of said portions being adapted to transmit a torque to the camshaft, and means for transmitting said torque to the pump. Said second axial portion (9) is provided with a housing (18) extending along said axis and designed to receive a means for drawing from the pump adapted to draw a lubricating fluid directed into the camshaft so as to provide a fluid communication between the camshaft and the pump.
