Patent ID: 7316425

Claim:
A quick connector comprising: a latch, a female part ( 1 ) with a stepped bore having a first section ( 2 ) suitable for sealingly receiving an endpiece ( 25 ) of a male part ( 21 ), and a second section ( 3 ) of larger diameter suitable for receiving an external collar ( 22 ) of the male part ( 21 ) beyond the latch, the latch being constituted by a ring ( 5 ) having a through orifice ( 28 ) for passing the collar ( 22 ) and of diameter close to the diameter of the collar ( 22 ), the ring ( 5 ) being mounted in a housing ( 4 ) formed in the female part ( 1 ) in the larger-diameter section ( 3 ) of its bore to slide radially in the housing ( 4 ), in a direction perpendicular to the axis of the bore, between a rest and locking first position in which the through orifice ( 28 ) in the ring ( 5 ) is off-center from an axis of the bore, and a retracted, second position, in which the through orifice ( 28 ) is substantially coaxial with the bore, wherein the latch includes a locking indicator ( 8 ) mounted to slide radially in the ring ( 5 ) and relative thereto, in a direction perpendicular to the axis of the bore, and being movable under voluntary operation between a first reference position within the ring indicating that the collar ( 22 ) has gone past the ring ( 5 ), and a second reference position within the ring indicating that the male part ( 21 ) has been locked properly, the ring and the locking indicator further comprising mutual locking means ( 11 , 15 , 16 ) for selectively securing the locking indicator ( 8 ) to the ring ( 5 ) in each of the reference positions so that the locking indicator ( 8 ) and the ring ( 5 ) are prevented from moving relative to each other when the locking indicator is in one of the reference positions.
