A luer connector assembly is provided for enhancing the frictional engagement between medical devices such as syringes and needle assemblies. The assembly needle includes a female luer fitting having a passageway and a relatively soft, resilient member bounding the passageway. The passageway is also bounded by the body of the fitting, which is harder than the soft, resilient member. A male luer fitting inserted into the passageway engages both the soft, resilient member and the body of the female luer fitting. A method of manufacturing such a connector assembly is further provided. A first material is injected into a mold to form the body of a female luer fitting, the fitting including a passageway and a recess extending into the body. A second material is then injected such that is extends into the recess and bounds the passageway. The second material, when cool, is softer than the first material.

L'invention concerne un ensemble raccord Luer conçu pour améliorer l'entrée en prise par frottement de dispositifs médicaux tels que des seringues et des ensembles aiguille. L'ensemble aiguille selon l'invention comprend un raccord Luer femelle comportant un passage et un élément élastique, relativement souple délimitant ledit passage. Ce dernier est également délimité par le corps du raccord, qui est plus dur que l'élément élastique et souple. Un raccord Luer mâle inséré dans le passage entre en prise non seulement avec l'élément élastique et souple mais aussi avec le corps du raccord Luer femelle. L'invention se rapporte également à un procédé de production d'un tel ensemble raccord, comprenant les étapes consistant à injecter une première matière dans un moule pour former le corps d'un raccord Luer femelle comportant un passage et un évidement s'étendant dans le corps ; et à injecter une seconde matière de manière à ce qu'elle s'étende dans l'évidement et délimite le passage. Une fois refroidie, la seconde matière est plus souple que la première matière.
