Patent attributes
A quick coupling device comprising a body (5) axially subdivided into a link section (6) for linking to a first duct (1), and a connection section (7) arranged to receive in leaktight manner one end of a second duct (2), the body being associated with a retaining member (22) possessing tabs (24) that are elastically deformable between a state of gripping an outer bead (4) on the end of the second duct, and a state of releasing the bead, the retaining member being mounted on the body to turn between a free deformation position in which the tabs can deform between their two states, and at least one holding position in which the tabs cooperate with a surface (20, 21) that is secured to the body and that holds the tabs in one of their two states.
