A coupling part constituting the male or female part in a quick coupling comprises an inner, longitudinally displaceable unit positioned in an outer part of the coupling part, the inner unit being adapted in a deactivated position thereof to confine the media pressure in a first chamber arranged in the outer part of the coupling part and in an actuated position to open or keep open an access for media to a second chamber in the outer part. Pressure-reducing members actuable upon coupling together of the male and female parts and allowing for the coupling even at high media pressures, and including a lead-off channel for media pressure and a shut-off element positioned in the channel, and actuable by the end face of the other coupling part through an actuation member. The actuation member is sealed-off or positioned in the coupling part in order to prevent lead-off media from reaching the end face of the coupling part. The lead-off channel on both side of the shut-off element is connectable to the first and the second chambers and upon actuation of the pressure-reducing member, the first and second chambers communicate through lateral connections in the inner unit the lead-off channel and the opened shut-off element whereby accompanying decompression of the pressure in the first chamber facilitates the longitudinal displacement of the inner unit, as a result of which it is possible to obtain leakage- free connection of the coupling parts in the presence of any media pressure.
