The coupling comprises coupling housing (1) with coupling member with allow insertion of a nipple memeber (6), and is positioned and fixed in the coupling housing provided with a ring (8) adjacent the end of insertion. The ring is situated in a ring groove for radial fixations of the nipple member. The coupling housing further comprises a sealing ring (2) situated after the balls (3) when seen from the end of insertion of the nipple member. The fixing member (8) radially retaining the nipple member is spaced from the sealing ring (2) being of a radius larger than the radius of the nipple member. The coupling housing and the nipple member are further provided with means (9,10) retaining them in one or more mutual positions in the circumferential direction.
