Abstract: A permanent repair clamp for pipes is adapted to be installed over a single or double ended pipe bell in a range of sizes. The device essentially comprises separately formed opposing clamp sections or body portions of semi-cylindrical formation with leak-proof interface gasketing between the clamp sections and between such sections and the pipe on which the device is installed. A spanning type arcuate connector or connector sections interlocks rigidly and positively with one side of one clamp section and is adjustably connected rigidly with the same clamp section at approximately the opposite diametrical side thereof, whereby the two clamp sections may be effectively and permanently secured in sealing relationship to a leaking pipe.
