ABSTRACT:
The device for providing a leak-tight coupling between a flexible tube and a rigid coupling connector comprises two coaxial components adapted to fit one inside the other. One component is mounted within the flexible tube while the other component is fitted around the tube. Longitudinal ribs formed on one component are adapted to cooperate with longitudinal grooves in the other component at the time of interengagement of the two components. The end of the tube is thus clamped and securely held in position.
