A coupling for unthreaded pipes of a sprinkler system, which permits the replacement of a small damaged pipe section without bending the pipes already emplaced in the ground. One coupling includes an end cap that can be installed on the end of a first pipe to be joined, and a sleeve which can slide over the second pipe and over the end cap for adhesive mounting thereto. A flexible wedge ring is sandwiched between the sleeve and cap.
