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, and means ( 19, 24, 25 ) for engaging it in leaktight manner, the engagement means comprising: at least one arm ( 19 ) extending axially from the connection section and having a free, gripper end ( 20 ) for gripping the pipe end, the arm being elastically deformable between a gripping state and a release state for releasing the pipe end; and a holding ring ( 25 ) connected to the connection section to receive a portion of the pipe end and to pivot between a position allowing free deformation of the arm, and at least one holding position in which a surface of the ring holds the arm in one of its two states.
