A perfusion tip for a flexible bag for medical use includes a tube formed in two tubular coaxial parts separated by a transverse pierceable membrane. The tube is provided on its external periphery with an annular projection delimiting an upstream tip portion adapted to be introduced in and fixed to by welding a portion secured to the flexible bag to be equipped, and a downstream tip portion adapted to receive a perfusion line. The tube also includes a ring engaged within the upstream portion and adapted, because of its hardness, to serve as a mandrel during production of the weld between the periphery of the upstream portion and the portion of the bag in which this upstream portion has been introduced, and a cover that caps the downstream portion and is adapted to ensure maintenance of the sterility of the tube while permitting access thereto.
