Abstract: A fluid transfer system includes Luer male and female connectors. The male connector has a main body with a longitudinal internal opening and an internal threading; the female connector has a main body containing an internal channel for the passage of fluids, a collar that surrounds at least a portion of an end of the main body, and external threading on the portion that is surrounded by the collar. The corresponding threadings are configured to engage and ensure a secure fit between the male and female connectors. An external surface of the male connector at the end where the threading is located forms a conical male portion, the internal surface of the collar of the female connector forms a conical female connecting surface, and the conical male portion is configured to fit against the conical female connecting surface and onto the collar when the male and female connectors are fitted together.

Abstract: 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.

Abstract: A system for transferring medical fluid includes a male Luer connector and a female Luer connector, the male Luer connector including a collar surrounding at least part of a male conical portion whose outer surface is supported against the female conical connection surface of the female Luer connector during the assembly of the connectors. The maximum inside diameter at the entrance to the collar of the male Luer connector is strictly less than the smallest outside diameter of a standard female Luer connector or one according to ISO 594-2. The female Luer connector includes a collar surrounding at least part of the female conical connection, this collar having an inside diameter greater than or equal to the outside diameter of the collar of the male Luer connector, to engage and at least partially cover the collar of this male Luer connector during the assembly of the connectors.
