摘要

The connection has a connecting piece (2) and a coupling piece (3) to which it can be sealed. The connection is an insertion connection, and the connecting piece has a locking ring (4) and a pre-tension ring (5) pushing the locking ring forward at least when the insertion piece is not inserted. In the engaged in state, the locking ring is pushed radially outwards and engages in a locking contour in the coupling piece.
