Abstract

A plug-in coupling for pressure application systems, including a receiving component, a connector component with a connecting shaft, an expanding cylinder supported on the connecting shaft between a radial step and a limit stop, and a spring unit initially supported on the expanding cylinder. The receiving component defines an opening and has a holding element, which is biased in a closed position and movable to an opened position. The connecting shaft of the connector component can be inserted into the opening of the receiving component along an insertion direction thereby engaging the radial step with the holding element to prevent loosening of the connector component from the receiving component. In this position, the expanding cylinder is located between the spring unit and the limit stop. The spring unit can be guided over the expanding cylinder in a direction opposite the insertion direction and the expanding cylinder can be moved along the insertion direction thereby disengaging the radial step from the holding element to allow release of the connector component from the receiving component.
