Abstract

Un joint de tuyau mâle est adapté de façon à ne pas être soumis à la résistance de la pression interne du joint de tuyau femelle lorsqu'il est inséré dans un joint de tuyau femelle, et de façon à ne pas être éjecté par la pression interne du joint de tuyau femelle lorsqu'on l'extrait du joint de tuyau femelle. Un joint de tuyau femelle comporte un élément du type tuyau côté amont (14), une unité clapet (26), une unité de retenue de clapet (40), un élément du type tuyau intermédiaire (52), un joint de tuyau mâle qui reçoit un élément du type tuyau (60), un élément de pression (70), et un élément de prise (80). Lorsqu'un joint de tuyau mâle (12) est inséré dans l'élément de type tuyau qui reçoit le joint de tuyau mâle et qu'il est enfoncé plus loin dans l'élément de type tuyau recevant le joint de tuyau mâle alors qu'il est en prise avec l'élément de type tuyau intermédiaire et qu'il pousse ce dernier, des éléments de verrouillage (62) sont alignés avec une cavité de réception d'élément de verrouillage (12a) ménagée dans le joint de tuyau mâle, l'élément de pression est libéré de l'élément de type tuyau intermédiaire qui a été enfoncé par le joint de tuyau mâle, pour presser les éléments de verrouillage, l'élément de type tuyau intermédiaire prend une position d'interruption de la communication avec l'air extérieur dans laquelle l'élément de type tuyau intermédiaire forme un espace de communication (56) entre l'élément du type tuyau intermédiaire et l'unité clapet, et l'élément de prise est libéré de l'élément de retenue de clapet, pour permettre à l'élément de retenue de clapet de prendre une position de libération côté aval.
