<p>Coupling for pressurized medium, comprising a stud member (1) and a socket member (2) into which the stud member can be inserted axially, whereby the stud member (1) and the socket member (2) can be mutually locked in a completely coupled position by means of a locking ring (5) which can be brought into engagement with circumferential locking ring grooves (11, 10) in the stud member (1) and in the socket member (2), and the stud member (1) and the socket member (2) have circumferential contact surfaces and/or grooves (8, 9; 6, 7) for two sealing rings (3, 4). A second circumferential ring groove (14) in the stud member (1) contains a safety ring (12), which also is in engagement with a separate groove (13) in the socket member (2), said groove (13) having a larger axial extension than the safety ring (12) and is situated such that when the stud member (1) and the socket member (2) are in a normal coupled position, and the locking ring (5) is in engagement with the locking ring grooves (11, 10) in the stud member (1) and the socket member (2), the safety ring (12) is situated in an axial distance from the axially outermost delimitation of its groove (13) in the socket member (2). Thus, the safety ring (12) is only effective when the stud member (1) and the socket member (2) are incompletely coupled together.</p> |
