Coupling devices for quick connection and disconnection of fluid conduits are disclosed including a first coupler with a recessed seat and a seat passage hole communicating with the seat, a second coupler with a protruding portion for insertion into the seat when the two couplers are connected, and a seating surface for sealing contact with the seat in the first coupling. The two couplers are pivotable between angled and aligned relationships, and the apparatus includes a tap on the second coupler to permit a valve body opposite the seat to adopt a closed position when the two couplers are in an angled relationship and to bring the valve into an open position when the two couplers pivot into an aligned position.
