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.
