Abstract
The disclosed bifurcated (fork-like) device is for use in a tube coupler to hold male and female members in sealing contact with one another. Each rail of the device has a laterally-outwardly-extending "hook-like" projection. When used in a coupler, such projections engage retention shoulders to retain the device on the coupler. Guide members help urge the projections toward such shoulders. A related tube coupler has a locking mechanism which is biased toward and automatically engages the device when such device is pushed into the de-coupling position. The coupler also has a trip surface which urges the mechanism to its unlatch position when the male member and the female member are moved to sealing contact with one another. Unlatching the mechanism permits the device to return to its coupling position.
