<p>The insertion coupling (1) has two parts (2, 3), one with a projection (4), running surface (5) and stop surface (6), and other with an elastic ring (7) on webs (8). There is an assembly indicator (13) with at least two arms (15) locked to one of the webs, as long as the ring is not locked behind the stop surface. And a projection presses the arms away from each other so that they come free of the webs when the ring is locked behind the stop surface.</p> |
