ABSTRACT:
A tube coupling includes a coupling body having a throughway open at one end to receive an end portion of a tube. A seal encircles the throughway to seal with the outer face and end of the tube. A cap mounted on the body has a tube locking device to engage and hold the tube in the coupling body. The cap and body have interengaging structure which guide the cap on the body for rotation and simultaneous axial movement between a first position on the coupling body and a second position further along the body. As such, when the cap is in the first position the tube can be inserted through the cap into the seal in the throughway and held therein by the locking device and on rotating the cap into the second position, the tube held by the locking device is forced against the seal in the throughway.
