<p>The coupling (20) has a pipe socket (24) introduced in end sections of pipes (12), which are introduced into a receiving chamber (32). A sleeve (30) is partially arranged around a base body (22), and an annular shoulder (28) is provided at an end of the pipe socket. A retaining element (40) outwardly engages the pipes, and resists movement of the pipes out of the receiving chamber. An inner retaining unit is arranged in an annular groove (48) of the pipe socket and is formed by a meander-like ring (46). The sleeve and the retaining element are formed as single-piece.</p> |
