Patent ID: 7845685

Claim:
An instant coupling device for coupling a pipe end to a circuit element, the device comprising: a body ( 10 ) axially subdivided into a joining section ( 11 ), for joining to the circuit element, and a connection section ( 12 ) provided with a housing ( 14 , 15 ) for receiving the pipe end within the connection section; and engagement means ( 19 , 24 , 25 ) for engaging the pipe end in leaktight manner, wherein the engagement means comprise at least one arm ( 19 ) extending axially from the connection section and having a free gripper end ( 20 ) for gripping the pipe end, said at least one arm being elastically deformable between a gripping state and a release state for releasing the pipe end, and a holding ring ( 25 ) having a structure arranged to be axially received within the connection section and to receive a portion of the pipe end and to pivot between a position allowing free deformation of said at least one arm and at least one holding position in which a surface of the ring holds said at least one arm in one of the gripping state and the release state.
