  • Publication number: 20230042410
    Abstract: Device for connecting a tube end section, comprising: a tubular body defining a channel provided with retaining means including a hooking element for engaging an outer surface of the tube end section and an annular seal for gripping the outer surface of the tube end section. The device comprises at least a first arm having an end arranged in the channel to be actuated by the tube end section downstream of the retaining means to make a portion of the arm a connection control that which is detectable from outside the body.

  • Patent number: 7762593
    Abstract: A ball coupler having a longitudinal axis and including a male tubular endpiece; a female tubular endpiece; and a tubular sleeve extending the female endpiece and presenting slots for forming a cage for retaining balls for blocking the male endpiece in the female endpiece. A grip is coaxial about the sleeve and mounted to turn about the longitudinal axis of the coupler between at least two angular positions relative to the sleeve, the grip having a housing for each ball. A resilient return device urges the grip into its first position, including in the grip, a ring that is constrained to turn with the grip and that is movable axially relative thereto.

  • Publication number: 20090021007
    Abstract: The invention relates to a ball coupler having a longitudinal axis and comprising: a male tubular endpiece; a female tubular endpiece; a tubular sleeve extending the female endpiece and presenting slots for forming a cage for retaining balls for blocking the male endpiece in the female endpiece; and a grip coaxial about the sleeve and mounted to thereon to turn about the longitudinal axis of the coupler between at least two angular positions relative to the sleeve, said grip possessing means for housing each ball; and resilient return means for urging the grip into its first position, which means comprise, in the grip, a ring that is constrained to turn with the grip and that is movable axially relative thereto, said ring presenting two end surfaces, one of which faces towards a shoulder of the sleeve for slidably bearing thereagainst to co-operate in reversibly transforming turning movement of the grip into an axial movement of the ring relative to said grip, and the other of which forms the bearing face
