Abstract
A tube coupling includes a coupling body () having an open ended throughway () to receive a tube (). A collet () is located in the open end of the throughway having a ring () and a plurality of flexible arms () extending into the throughway. The throughway has a tapered cam surface () convergent towards the open end and the collet arms have heads () at their distal ends for engaging both the cam surface and a tube extending through the collet into the throughway to be compressed against the tube by the cam surface with outward movement of the collet with respect to the throughway to secure the tube in the throughway. A collet lock () is rotatably mounted on the coupling body having one rotary position in which the lock holds the collet () and another rotary position in which the collet can move axially.
