ABSTRACT:
A pipe joint consisting of first and second pipes having ends juxtaposed to provide a fluid tight interconnection therebetween. An outer surface of the first pipe defines a first circumferential coupling groove and a first circumferential seal groove disposed between the first coupling groove and the connected end of the first pipe. An outer surface of the second pipe defines a second circumferential coupling groove and a second circumferential seal groove disposed between the second coupling groove and the joined end of the second pipe. Fitted over the outer surfaces of the first and second pipes is a resilient sleeve covering the first and second seal grooves. A clamp assembly with inward projections overlays the sleeve and is radially collapsible to forcibly engage the resilient sleeve. Engaging the clamp assembly is a latch mechanism that exerts thereon inwardly directed forces that retain the inward projections within the first and second coupling grooves and o-ring portions of the resilient sleeve within the first and second seal grooves.
