Quick coupling for connecting fluid carrying lines, in particular in a commercial aircraft

A quick connector (2) of fluid-conducting for connecting lines has a first coupling housing (4) having a first conduction terminal (32) and a first connecting surface (6) with a first coupling aperture (8), a second clutch housing (36) having a second line connection (60 ) and a second connecting surface (56) having a second coupling aperture (40), arranged one (in the first clutch housing 4) first sealing means (9) which is adapted to close the first coupling aperture (8) fluid-tightly and a second in which arranged clutch housing (36) second sealing means (37) having at least one via the second coupling opening (40) projecting sealing component (46). The second sealing means (37) is adapted to close the second coupling aperture (40) fluid-tightly and in merging of the first coupling housing (4) and the second coupling housing (36) into a coupling position by means of the sealing component (46), the first sealing means (9 urging) to an open position. A flow direction of the lead terminal (32, 60) and the coupling aperture (8, 40) of the coupling housing (4, 36) are each non-concentric to each other and by at least one in the relevant clutch housing (4, 36) integral cavity (11, 34, 80, 65) in fluid communication.
