Abstract
A tube coupling comprises a coupling body having an open ended throughway, an annular shoulder in the throughway, an 'O' ring seal located against the annular shoulder and a collet located in the open end of the throughway. The collet has a head projecting out of the throughway and resilient arms extending into the throughway to engage a tapered cam surface adjacent the open end. A ring is disposed in the throughway between the collet and 'O' ring seal. The side of the ring adjacent the collet has a ramp around its inner periphery to engage the ends of the collet arms when the collet is depressed into the throughway and the other side of the ring has a ramp around its inner periphery to engage and hold the ‘O’ ring seal in alignment in the throughway when the collet is depressed into the throughway.
