A fluid connection assembly (10) includes a metal tube (22) having a flared end and a plastic manifold (12) having a port (14). The port (14) includes an annular collar (16) and an annular recess (18) that receives a seal (20). The metal tube (22) is arranged over the port (14) and engages the seal (20). The flared end of the metal tube (22) abuts the annular collar (16) of the port (14) when the metal tube (22) is installed. A plastic retainer (28) is molded over the annular collar (16) of the port (14) and the flared end of the metal tube (22) to retain the metal tube (22) axially on the port (14) of the manifold (12). Alternately, the end (221) of the metal tube (222) is crimped to secure the metal tube (222) to the port (214) of the manifold (212).

L'invention concerne un ensemble connexion fluidique (10) qui comprend un tube métallique (22) pourvu d'un bout évasé et d'un collecteur plastique (12) comportant un orifice (14). L'orifice (14) comprend un manchon annulaire (16) et un évidement annulaire (18) qui reçoit un joint (20). Le tube métallique (22) est installé sur l'orifice (14) et vient en contact avec le joint (20). Le bout évasé du tube métallique (22) s'aligne bout à bout avec le manchon annulaire (16) de l'orifice (14) lorsque le tube métallique (22) est installé. Un dispositif de retenue en plastique (28) est moulé par-dessus le manchon annulaire (16) de l'orifice (14) et le bout évasé du tube métallique (22) afin de retenir le tube métallique (22) axialement sur l'orifice (14) du collecteur (12). Dans une variante, l'extrémité (221) du tube métallique (222) est serti de façon à fixer le tube métallique (222) sur l'orifice (214) du collecteur (212).
