Claim:
1. A coupling part for coupling with a corresponding coupling part of a coupling for a pressure medium line comprising (a) a housing having a flow channel and a coupling axis; (b) a sleeve-shaped closing valve displaceable back and forth in the axial direction within the flow channel for closing off the flow channel in an uncoupled state of the coupling part, wherein the closing valve has a closed valve position closing off the flow channel and an open valve position not closing off the flow channel; (c) a plunger displaceable back and forth in the axial direction within the flow channel to drive the closing valve in a valve opening direction during a coupling process; and (d) a plunger pin disposed between the plunger and the closing valve within the flow channel for transferring movement of the plunger in the valve opening direction to the closing valve; wherein the plunger pin is connected with the closing valve so as to be non-displaceable in the axial direction.
