Au moins une plaque déflectrice de support (106) est située entre le tuyau intérieur (104) et le tuyau extérieur (102). Ainsi un passage de transfert (A) est formé dans le tuyau intérieur (104) et un passage de transfert (B) est formé entre le tuyau intérieur (104) et le tuyau extérieur (102), ce qui permet de transférer des liquides ou des gaz différents de sorte que ces liquides ou que ces gaz soient séparés les uns des autres. En outre, un dispositif final (200) est raccordé au tuyau extérieur (102) et au tuyau intérieur (104). Ce dispositif final (200) comprend un corps cylindrique (210) combiné à une première unité couvrante (220) pour l'accouplement d'une extrémité du corps (210) au tuyau extérieur (102), et une seconde unité couvrante (230) pour l'accouplement de l'autre extrémité du corps (210) et pour la réception d'une unité d'aspiration (234). L'unité d'aspiration (234) est équipée d'un arbre d'aspiration (234b) dont une extrémité est reliée au tuyau intérieur (104) et l'autre extrémité est reliée à un raccord fileté (236) de tuyau intérieur de manière à pouvoir transférer les fluides ou les gazes transférés par le passage de transfert (A). En outre, le corps (210) comprend un raccord fileté (240) de tuyau extérieur destiné à acheminer les fluides ou les gaz transférés par le passage de transfert (B) vers l'extérieur, par formation d'un orifice de montage (216) sur le corps. Selon l'invention, les tuyaux ne s'entremêlent pas pendant leur utilisation, et par conséquent l'invention présente l'avantage d'une efficacité d'utilisation accrue, et permet d'aspirer différents liquides ou gaz de manière séparée.
