The invention relates to an administration tip for a flexible for medical use. The inventive administration tip is of the type that comprises a chamber (2) consisting of two co-axial, tubular parts which are separated by a piercable, transverse membrane (5). The tip is characterised in that the external periphery of the chamber (2) is provided with a continuos or non-continuous annular projection (9). Said projection defines: (i) an upstream part of the tip which is intended to be inserted in, and welded to, an integral part of the flexible bag to be equipped; and (ii) a downstream part of the tip which is designed to receive a venous line. The invention is also characterised in that it comprises a ring (4) which is inserted inside the upstream part and which, owing to the hardness thereof, can act as a mandrel while the periphery of the upstream part is being welded to the flexible bag in which it has been inserted. Moreover, the invention comprises a cover (3) which is placed on the downstream part and which ensures that the chamber (2) remains sterile, while providing access thereto. The invention is suitable for flexible bags that are used for medical purposes.
