ABSTRACT:
A first quick-coupling part can be brought into interaction with a second quick-coupling part via an interaction portion. The quick-coupling parts are held together with locking members. The interaction portion is designed with a surface layer which brings about an essentially crack-free flexibility for the locking members in spite of high actuating forces. One or more underlying layer(s) has (have) greater hardness than the surface layer, and the combination of said layers gives the necessary resistance against high media pressure.
