ABSTRACT:
A conduit coupling is provided having a body member with an axial bore which is adapted to receive the end of a conduit. A fastening member also includes an axial bore and is adapted to surround the conduit and be secured to the body member. A sleeve having an axial bore is also adapted to surround the conduit and is axially positioned between the fastening member and the body member. The sleeve includes a frangible web for separating the sleeve into a plurality of elements in response to the application of an axially compressive force on the sleeve. Once the sleeve is separated, the plurality of sleeve elements cooperate with the fastening member and the body member to create a mechanically strong fluid-tight joint between the body member and the conduit.
