A fluid transfer system includes a Luer female connector having a main body containing an internal channel for passage of fluids and a collar surrounding at least a part of the end of the main body, and a Luer male connector having a main body with a longitudinal internal opening. The main body of the female connector contains a first threading on at least a part of the external surface of that portion that is surrounded by the collar, located at least in part facing an internal surface of the collar; one of the ends of the main body of the Luer male connector contains a second threading on at least a part of its internal surface delineating the longitudinal internal opening, which engages into and fits in the first threading to ensure joining between the Luer male and female connectors.

1. A fluids transfer system for medical use, comprising a Luer male connector (10) and a Luer female connector (11), wherein said Luer female connector (11) comprises a main body (14) containing an internal channel (15) for the passage of said fluids, and a collar (12) surrounding at least a part of
1. A fluids transfer system for medical use, comprising a Luer male connector (10) and a Luer female connector (11), wherein said Luer female connector (11) comprises a main body (14) containing an internal channel (15) for the passage of said fluids, and a collar (12) surrounding at least a part of the end of the main body, andsaid Luer male connector (10) comprises a main body (18) with a longitudinal internal opening (19, 21), and wherein: the main body (14) of the female connector contains a first threading (16) on at least a part of the external surface of that portion that is surrounded by the collar (12), located at least in part facing an internal surface of the collar (12),one of the ends of the main body (18) of the Luer male connector (10) contains a second threading (20) on at least a part of its internal surface delineating the longitudinal internal opening (19, 21), which engages into and fits in the first threading (16) to ensure joining between the Luer male and female connectors,at least the external surface of the Luer male connector (10) end where the second threading (20) is located forms a conical male portion (24) having a conical axis of revolution, while the interior surface of the collar (12) of the female connector forms a conical female connecting surface (13) having a conical axis of revolution, so that the external surface of the male conical part (24) fits against the conical connecting surface of the collar (12) of the Luer female connector (11) to provide a sealed joint when the Luer male and female connectors are fitted together. 2. The system according to claim 1, characterized in that at least one of the Luer male (10) and female (11) connectors is made of a single piece and of plastic material. 3. The system according to claim 1, characterized in that the internal channel (15) of the Luer female connector (11) has a diameter at least equal to the diameter of the internal channel (15) of the male conical portion (24) of the Luer male connector (10) set out in ISO standard 594-2. 4. The system according to claim 1, characterized in that the Luer male connector (10), and/or the Luer female connector (11), contains an internal wall located in its internal longitudinal opening (19, 21), respectively and/or in its internal channel (15), with the internal wall comprising an orifice for the flow of fluids. 5. The system according to claim 4, characterized in that the Luer male connector (10) with an internal wall containing an orifice in its internal longitudinal opening (19, 21), which orifice has a truncated portion located at the end of the longitudinal internal opening (19, 21) that has a second threading (20), and the end of the main body of the Luer female connector (11) is conical so that with this end being located near the orifice of the said internal wall, fluids are directed through the orifice. 6. The system according to claim 4, characterized in that the Luer male connector (10) with an internal wall containing an orifice in its longitudinal internal opening (19, 21), which orifice has a portion protruding from the wall being located at the end of the longitudinal internal opening (19, 21) that comprises said second threading (20), with said protruding portion having an external diameter inferior to the diameter of the internal channel (15) of the main body of the Luer female connector (11) so that it can be received in the internal channel (15) when the Luer male and female connectors are joined together in order to direct said fluids through the orifice. 7. The system according to claim 4, characterized in that the internal channel (15) of the Luer female connector (11) has a diameter at least equal to the diameter of the internal channel (15) of the male conical portion (24) of the Luer male connector (10) set out in ISO standard 594-2. 8. A medical device that includes at least one recipient containing fluids for medical use equipped with the fluids transfer system according to claim 1. 9. The system according to claim 2, characterized in that the internal channel (15) of the Luer female connector (11) has a diameter at least equal to the diameter of the internal channel (15) of the male conical portion (24) of the Luer male connector (10) set out in ISO standard 594-2. 10. The system according to claim 2, characterized in that the Luer male connector (10), and/or the Luer female connector (11), contains an internal wall located in its internal longitudinal opening (19, 21), respectively and/or in its internal channel (15), with the internal wall comprising an orifice for the flow of fluids. 11. A medical device that includes at least one recipient containing fluids for medical use equipped with the fluids transfer system according to claim 2.
