ABSTRACT:
A coupling device includes male and female telescoping members that are inserted into a fluid carrying hose or conduit. The coupling device includes an O-ring for providing fluid tight seal and a frangible locking ring that will separate when oppositely directed forces exceed a predetermined threshold. The locking ring includes a split so that it can be compressed to a smaller diameter for installation and, in the preferred embodiment, a plurality of frangible radial tabs. In an alternative embodiment, the ring may have a radially extending flange with a parting groove at the juncture of the ring and flange. One of the coupling device members includes a groove that holds the ring and the other member includes a groove that receives the radial tabs or flange.
