Connector

The connector has connector assemblies (1, 5) with central longitudinal axes (6) and axial passage channels. A dirt lip (15) rests in a closed condition of the connector at an outer surface (19) of one connector assembly and comprises a front-side surface (20) at free ends. A set of radial extensions (r1, r2) of the front-side surface of the dirt lip is viewed in a direction of one central longitudinal axis and overlaps with another set of radial extensions (r3, r4) of a side wall (12) of a sealing groove (10). The dirt lip with the front-side surface is supported at the wall of the groove.
