Abstract: An apparatus to provide a threaded coupling for a pipe to enable the pipe which has had its threads broken to be joined to a mating threaded pipe. The threaded coupling permits the coupling to be affixed to the pipe when the pipe is located in a difficult to reach area. The invention is used with a pipe which has been broken in a house wall and it is desired to not have to rip out the entire wall to get at the pipe. A transverse opening is drilled in the pipe after a small section of wall adjacent the threaded end has been removed and a pin inserted into the opening. Thereafter, a collar with a recessed wall to accommodate the head of the pin and a shelf to abut the head of the pin serves to form a secure retaining means onto which a gasket to seal leaks and a pressing ring for engagement with a mating coupling is affixed so that the broken pipe can be joined to a mating pipe.
