Abstract
A plug-in safety coupling for pressure lines including a coupling socket (1) having a blocking member (3) pivotally mounted therein and a plug (2) insertable therein for pressureless coupling and uncoupling. The blocking member (3) is secured against pivotation at least in the flow position by means of at least one bolt or cam. The bolt or cam (67) is displaceably guided at the coupling socket (1), and in the blocking position engages into a bore or a recess in the blocking member (3). The blocking member (3) has a through bore extending perpendicularly to its pivotal axis into which an adapter (4) having a through bore, is insertable and fits tightly and sealingly and where an internal surface of the adapter (4) is shaped to receive the plug (2) to be inserted.
