Abstract:
1. A luer fitting connector assembly comprising: a male or female luer fitting member having a longitudinal axis and adapted for connection at a forward end thereof with a female or male luer fitting, respectively, the luer fitting member comprising a conical restraining surface, the conical restraining surface comprising a rim providing an end surface facing distally that is approximately orthogonal to said longitudinal axis, said luer fitting member having a rotary mount adjacent said rim defining a recess with a cylindrical rotational surface; and a one-piece locking member comprising a hollow central lumen, an annular, inwardly protruding plateau shaped protrusion providing an end surface facing proximally that is approximately orthogonal to a longitudinal axis of said lumen, and a body that extends axially beyond at least a portion of the conical restraining surface and toward the forward end of the luer fitting member; wherein the locking member can in assembly of the connector assembly be moved from a rearward end of the luer fitting member toward the forward end thereof, with said protrusion snapping over said conical restraining surface to position said rim end surface and said protrusion end surface to engage each other to provide a positive stop against separation of the locking member from the luer fitting member, and to position said protrusion in said recess such that said locking member is freely rotatable with respect to said rotational surface.
