A tube release apparatus for use with a coupling that includes a tube gripping means (10, fig 1) and a release element 14 comprises a first release member 202 having a contact surface for engagement with the release element 14 of the tube coupling apparatus and a second release member 212 engageable with the body of the tube coupling apparatus. Both the first and second release members 202, 212 include respective threaded portions so as to be capable of threaded engagement with each other. When in threaded engagement, rotation of one of the release members 202, 212 in a predetermined direction is capable of causing the contact surface of the first release member 202 to engage the release element 14 of the tube coupling thereby urging the release element 14 to engage the tube gripping means (10, fig 1) so as to urge it out of engagement with the tube 22. |
