Abstract

A plug-in coupling for pressurized systems having two coupling components (2, 4), namely a receiving component (2) and a connector component (4). The connecter component (4) includes a connecting shaft (6) which is inserted into a locator opening (8) of the receiving component (2) and is sealed around the perimeter and arrested against loosening by a holding element (20) situated in a recess (22) of the receiving component (2), first in a partially inserted, incompletely sealed, pre-locked position and secondly in a fully inserted, perfectly pressure sealed full lock-in position. The holding element (20) has arresting elements (28, 30) each of which engage behind a locking edge (24) of the connector component (4) when a lock-in connection (28, 24; 30, 24) is formed. The holding element (20) is relatively movable axially in the recess (22) of the receiving component (2) in such a way that at least in a full lock-in position, at least one arresting element (30) can be transferred, by shifting of the holding element (20) against the direction of insertion, from an unlocked position in which the respective lock-in connection (28, 24; 30, 24) can be released, to a locked position in whi…
