ABSTRACT:
The disclosure relates to a tube coupling comprising a coupling body, having a throughway open at one end to receive a tube. A first collet is mounted in the throughway to grip the tube and resist extraction of the tube from the throughway. A cap is mounted to extend over the open end of the coupling body to house a second collet arranged head to head with the first collet. The second collet is engageable with an annular abutment on the tube to retain the tube in the coupling body. A single release means in the form of plunger elements is provided on the cap to act on the collets to allow release of the tube from the coupling body.
