ABSTRACT:
A plug-in connector comprising a base body (6), an annular sealing element (12), a clamping ring (50) and an annular body (20) which can be connected to the base body (6). A pipe end (4, 5) against which the sealing element (12) is arranged in a sealing manner, can be secured in the plug-in connector by the clamping ring (50). The plug-in connector of the invention can be connected to an end (4, 5) of at least one pipe in a simple manner and with a high degree of functional reliability, excluding the risk of assembly errors. For this purpose, the sealing ring (12) is arranged in an annular groove (14) of the base body (6) and comprises two sealing beads (60, 62) which are situated against the inner surface of the inserted pipe end (4, 5) in the manner of two o-ring seals.
