Drainage sleeve for joining pipes, which being of the type consisting of a hollow cylindrical body in which the pipe is housed, essentially is characterized by internally presenting a series of longitudinal ribs equidistant from each other, with their bevelled ends and their central area provided with a small highlighted area, in such a way that the sections of the pipe penetrate at one end of the sleeve until reaching the lateral edges or step of the central projection of the ribs, leaving the pipe imprisoned on the outside through the edges to which the inner nerves give rise, giving rise to a cavity between the pipe itself and the sleeve for water penetration.
