摘要： 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 which release of the lock-in connection (28, 24; 30, 24) is prohibited.

摘要： A pipe fitting (1) for connecting a metallic pipe line (10), including a pipe union (4), which contains a receiving opening (8) for the pipe line (10), a swivel nut (6), which can be threadedly connected with the pipe union (4), as well as metallic cutting ring (18), which is disposed between the pipe union (4) and the swivel nut (6). The cutting ring (18) with an outer cone (30) acts jointly with an inner cone (28) of the pipe union (4) in such a manner, that, when the swivel nut (6) is tightened, it cuts into the material of the pipe line (10) with at least one cutting edge (32) and generates a form-fitting junction. The cutting ring (18) includes--where it joins an outer cone (30)--an essentially radial contact surface (38) for the purpose of limiting the tightening force, when it comes into contact with a face surface (40) of the pipe union (4). The cutting ring (18), in the transition region between the outer cone (30) and the contact surface (38), contains an elastomeric circumferential seal (44) in such a manner, that the circumferential seal (44), when it is in the assembled condition, is under an elastic pre-stress between the cutting ring (18) on the one hand, and at least one partial region of the interior cone (28) of the pipe union (4), which joins the face surface (40) on the other hand.
