Abstract: A coupling assembly including an endpiece defining a fluid flow passageway and being adapted to be secured to an outlet of a fluid-flow circuit, and a coupling member including a body defining at least one housing for receiving locking balls, a slider defining an axial wall of the at least one housing, a control member surrounding the body and slider and being provided with a ball-locking element that is movable between a rest position in which it and the slider, in an advanced position thereof, retain the locking balls in an innermost locking position, and a release position wherein the slider is movable to allow the locking balls to move both linearly and outwardly to an unlocked position thereof, and return elements for returning the control member to its rest position.

Abstract: A connection for ensuring a correct coupling of two conduits including two connectors adapted to be fitted one within the other along an axis of fit and which connectors include initially engageable portions that permit a controlled angular indexing of the two connectors as they are initially brought into engagement and which further include selectively adjustable elements that prevent a complete joining of the connectors if at least one of the adjustable elements of one of the connectors is positioned to block an opposing adjustable element of the other connector.

Abstract: The coupling assembly comprises an endpiece suitable for being secured to the outlet of a fluid-flow circuit, and a coupling member comprising a body, at least one housing for receiving said locking balls, a slider defining an axial wall of the housing, a control member provided with a ball-locking element that is movable between an active position in which it entrains the slider into its advanced position, and a release position, and return means for returning the control member into its released position, which return means are interposed between facing walls belonging respectively to the body and to the control member.

Abstract: The connection according to the invention comprises two elements adapted to be fitted in each other along an axis of fit and no-mistake means borne by the two elements and adapted to pair the two elements by complementarity of shapes. In order to facilitate manipulation of the connection elements to be fitted, and even easily to allow such manipulation by relatively insensitive robots, while simplifying management of the stocks associated with these connection elements, the connection further comprises means for angularly indexing the two elements, borne by the two elements and adapted to position the two elements angularly with respect to each other before the no-mistake means, at least partly connected to the two elements in removable and configurable manner, cooperate together during fit of these elements.

Abstract: A female element of a quick connection for removably joining two pipes through which a fluid passes wherein the element includes a body defining a housing for receiving a portion of a male endpiece. A retaining device is operable to selectively retain the endpiece in fitted configuration in the female element and includes a push-button which carries a lock for selectively locking the endpiece in the housing or for preventing the introduction of the endpiece in the housing.

Abstract: This invention relates to a female element of a rapid connection for removably joining two pipes through which a fluid passes, said element comprising a body defining a housing for receiving a part of a male endpiece and means for locking said endpiece in fitted configuration in said female element. The locking means are controlled by a press-button which bears controlled means, such as a cylinder controlling a bolt, for selectively blocking the locking means in configuration of hold of said part of the endpiece in the housing and/or in a configuration opposing the introduction of a part of an endpiece in said housing.
