A medical connector, of a female luer type, comprises an external tubular body (4) which contains an internal tubular body (2) free to rotate about an axis thereof. The external tubular body exhibits a screw-coupling surface. The internal tubular body exhibits a conical luer seal surface. An insert (5), which has a pawl (9) snap-fitted in a window (8) afforded on the external tubular body, constrains the two tubular bodies solidly to one another, in an axial displacement direction. The connector is used to connect a blood line to a blood port of a dialyser, preventing the blood line from twisting on itself and kinking [Figure 1].

L'invention porte sur un raccord médical, de type Luer femelle, qui comprend un corps tubulaire extérieur (4) contenant un corps tubulaire intérieur (2) à rotation libre autour d'un de ses axes. Le corps tubulaire extérieur comporte une surface de couplage par vis. Le corps tubulaire intérieur comporte une surface conique d'étanchéité de Luer. Un insert (5) comportant un cliquet (9) encliqueté dans une fenêtre (8) ménagée sur le corps tubulaire externe fixe solidement les deux corps tubulaires l'un à l'autre, dans une direction de déplacement axiale. Le raccord est utilisé pour relier une ligne sanguine à un orifice de sortie de sang d'un appareil de dialyse, empêchant la ligne sanguine de senrouler sur elle-même et de sentortiller [Figure I].
