ABSTRACT:
A plug-in coupling for pressure application systems, including two coupling components such as a housing component and a connector component. The connector component is sealed insertable into a locating opening of the housing component, and is arrestable against loosening by a locking device. The locking device has an elastically deformable holding element, which is located on the side of one coupling component in such a way that, in the inserted state, it engages behind an arresting step of the other coupling component, locking with positive fit, for arresting said connector component. The holding element is designed ring-shaped and comprises several individual annular segments and one concentric spring lock washer component which presses the annular segments with radially operating spring resistance that each annular segment can move radially against or through the spring resistance of said spring lock washer component during the plugging-in.
