The invention relates to a guide-tube with integral sealing for motor vehicle gearbox clutch release bearing, comprising a tubular sleeve able to be engaged axially around the input shaft of the gearbox and having a radial bearing surface made from one part, forming a plate for fixing the guide-tube to the outer face of the wall of the casing of the gearbox, and a sealing ring with a lip engaged inside the sleeve. The sealing ring with a lip comprises a reinforcing member (5) comprising a tubular bearing surface (6) able to be engaged by force in the tubular sleeve (1) of the guide-tube, the said tubular bearing surface (6) being extended at each of its ends by a radial bearing surface, one (7) directed towards the inside and at the end of which a sealing gasket with a lip (9) is made and the other (8) directed towards the outside and on which an annular sealing bead (13) is made, able to come into contact with the external face of the wall of the casing.
