ABSTRACT:
The disclosure relates to a tube coupling having a body with a throughway open at one or both ends to receive a tube. A collet is located in the throughway and a plurality of resilient fingers which engage an internal cam surface tapering in one direction towards said one end of the throughway to compress the fingers against the tube to grip and hold the tube when the collet is drawn in said one direction with the tube. An end of the collet projects from the throughway and can be depressed into the throughway to release a tube therefrom and an end cap is detachably mounted on the body to cover said open end of the throughway. The end cap has manually operable radially movable presser members for engaging the end of the collet projecting from the throughway for urging the collet into the throughway to release a tube from the body.
