The male (1) and female (2) coupling or only the one cone (5) of the male or female coupling are/is axially displaceable in relation to the threads (3) of the male and female couplings. With the axial displacement of the cone a valve component (6) is automatically opened or closed in relation to the flow channel (7) when the male and female couplings are coupled or uncoupled. |
