A connecting device for connecting a container (1) consisting of a sealed flexible bag (3) to an external duct (2) that includes a tube (4) with a connecting opening (5). A rigid tubular coupling (6) is loosely arranged within the flexible container (1) and comprises a frusto-conical projection (7) sized in such a way that it may be force-fitted into the opening (5). A user grasps the coupling (6) and places it against the inner surface of the bag (3) while placing the opening (5) of the external duct (2) against the outer surface of the bag (3), then axially presses on the coupling (6) so that it perforates the bag (3) and sealingly engages the opening (5). The fluid in the container (1) can then flow through the coupling (6) into the external duct (2).

[ I claim:] [1.] A device for connecting a flexible container (1) for fluid (14) to an external duct (2), comprising a flexible container (1), a coupling (6) and a tube (4), the container (1) being formed of a flexible bag (3) that can be welded to delimit at least one sealed compartment, the external duct (2) comprising the tube (4) with an axial passage (50) with a connecting opening (5), the tubular rigid coupling (6) being housed freely inside the compartment delimited by the flexible bag (3) and including an elongate axial projection (7) a free end (72) of which is sized to engage in the connecting opening (5) of the tube (4) of the external duct (2) and the other end of which is connected to a transverse push-base (8), rein the projection (7) has a frustoconical outside surface (10) with a larger base (71) adjacent the transverse push-base (8) and a smaller base forming the free end (72) of the projection (7), the flexible bag being adapted to stretch considerably before it ruptures, so that the smaller base of the free end (72) can deform the flexible bag (3) by causing a portion (33) of the flexible bag (3) to penetrate into the axial passage (50) of the tube (4) to a penetration depth (P) at the time of connection, the projection (7) having a cone angle (A) and a large diameter (D) adapted to assure good wedging of the projection (7) in the tube (4) when the portion (33) of the flexible bag (3) is engaged in the axial passage (50) of the tube (4).
