<p>A tube coupling to receive an hold a tube (T). The coupling comprising a coupling body (10) having a throughway with an 5 annular step (24) facing an open end (12) . An annular seal (25) is located in the coupling body adjacent to the annular step. An end cap (13) engages the coupling body and is axially moveable. A collett (17) in the cap has legs (20) with outer surfaces that engage with a tapered surface (23) 10 in the end cap to urge the legs inwardly to grip the tube. The seal (25) is compressed axially in response to the forward movement of the end cap (13) to cause the tube end to be pressed into sealing engagement with the seal end. A biasing member (28) provides a biasing force to urge the 15 legs (20) axially onto the tapered surface (23) when the cap is in the retracted position. *-*--**-***-"~**-i r - -,--.
