Plug-in coupling
First Claim
1. A plug-in coupling comprising:
- a base body;
an annular sealing element;
a clamping ring; and
an annular body which is connectable to the base body, whereinan inserted pipe end in sealing contact with the sealing element can be fixedly secured in the plug-in coupling by the clamping ring,the sealing element is arranged in an annular groove in the base body and has two sealing beads which contact an inside surface of the inserted pipe end,the annular groove of the base body has a radially outwardly directed holding body which engages in a radially inwardly arranged annular groove of the sealing element,the two sealing beads of the sealing element are substantially circular in cross-section, with their respective circular cross-sections located essentially tangential to a cylindrical inner surface of the sealing element and oriented essentially perpendicular to the cylindrical inner surface of the sealing element and parallel to a longitudinal axis of the sealing element,the two sealing beads are longitudinally separated by a connecting part having a length greater than a radius of either sealing bead circular cross-section, andthe annular groove of the sealing element is arranged between the two sealing beads, outside of a circumference of either sealing bead.

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.
