Patent ID: 6983958

Claim:
A device ( 10 ) for connecting a feed for a pressure fluid system comprising: a connector ( 30 ) having a head ( 35 ) received axially in a body ( 11 ) of a feed inlet ( 12 ) including a purge orifice ( 13 ), wherein the connector ( 30 ) is capable of being locked in a forward position engaged axially in the feed inlet body ( 11 ) by locking means ( 60 ), which includes a generally symmetrical U-shaped hairpin ( 60 ) having two transverse locking branches ( 62 ), the connector ( 30 ) and body ( 11 ) being unlocked from each other, in order to enable the connector ( 30 ) to be at least partly moved in a rearward direction axially out of the body ( 11 ), by elastic deformation of the locking means ( 60 ) which results from the mating cooperation that exists between at least part ( 66 ) of the transverse locking branches ( 62 ) and at least part ( 17 ) of the body ( 11 ) under the action of a releasing force exerted on the locking means ( 60 ) being in a locking position, in a transverse direction (T 1 ), and wherein at least one sealing ring ( 38 ) is arranged between the head ( 35 ) of the connector ( 30 ) and the feed inlet ( 12 ), wherein in the engaged position, the connector ( 30 ) sealingly obturates the purge orifice ( 13 ), the engaged position can be disengaged by acting on the connecting portion ( 61 ) of the hairpin ( 60 ), wherein, by pushing on a connecting portion ( 61 ) which connects the two transverse locking branches ( 62 ) of the hairpin ( 60 ) together, the connector ( 30 ) is able to occupy a purge position in which it is partly retracted axially towards the rear, wherein the feed inlet ( 12 ) is put into sealed communication with the purge orifice ( 13 ), and the purge position being maintained by the locking branches which are positioned in a groove ( 40 ) of the connector and in engagement on a radial rear shoulder ( 41 ), and wherein, by pulling on the connecting portion which connects the two transverse locking branches ( 62 ) of the hairpin ( 60 ), the connector ( 30 ) is adapted to be disengaged completely from the feed inlet, the locking means occupying an unlocking position.
