The present invention relates to a quick joint coupling for liquid tight joining of lines under high pressure and comprising a sleeve shaped female part and a male part being introducible into said female part, whereby a male part related to the female part comprises a cylindrical part being introducible into the female part the envelope surface of which presents a groove having a certain width, which groove receives a ring being axially displaceable between the two walls of the groove, which ring has substantially the same thickness as the depth of the groove, and which female part comprises a cylindrical space for receiving the cylindrical part of the male part, the envelope surface of said space is provided with at least a groove for receiving elastically movable locking means out off and into the cylindrical part, which means in a locking position cooperates with the edge of the groove being situated closest to the outer end of the male part and which locking means are displaceable out off their locking position by an movement of the ring towards said outer end edge, which movement is made possible by pressing the male part into the female part until the locking means are brought into a frictional engagement with the outer side of the ring, wherein the locking means (13) of the female part are arranged in a rotatably arranged means (10), which is rotatably arranged in relation to the female part (6) via a bearing (11).
