Abstract

Abstract The invention relates to a quick-acting coupling of the ball-catch type comprising a coupling housing (1) with coupling means and allowing insertion of a nipple member (6), which is positioned and fixed in the coupling housing provided with a ring (8) adjacent the end of insertion, said ring (8) being situated in a ring groove for radial fixatiosn of the nipple member (6), said coupling housing (1) further comprising a sealing ring (2) situated after the balls (3) when seen from the end of insertion of the nipple member (6). The fixing means (8) radially retaining the nipple member (6) is spaced from the sealing ring (2) being of a radius larger than the radius of the nipple member (6). The coupling housing (1) and the nipple member (6) are further provided with means (9, 10) retaining them in one or more mutual positions in the circum­ferential direction.
