<p>A nipple (1) is connectable or connected to a system (2) of pressurizable fluid (16). The first rapid-coupling part operates with a dual function in which, in a first function, the first rapid-coupling part can be coupled together with a second rapid-coupling part and in the coupling position of the parts fluid can be drained off to a first apparatus receiving the drained-off fluid and, in a second function, the first rapid-coupling part receives a probe-shaped unit, which is insertable in the first rapid-coupling part, for draining off the fluid to a quality-detecting apparatus or container apparatus connected to the probe-shaped unit.</p> |
