Key For 1 to 5 see Table 1 a Connector end b Tail end Figure 1 — Coupling assembly SIST EN 14423:2013

NOTE A distinction is made between the connector end and the tail end of coupling assemblies. The former is the part by which the coupling is connected to an appliance or pipe (for various types of connectors, see Table 2), while the latter (including the tail end fitting and clamp) is fastened to a hose (see 7.2 and 7.4).
