Abstract
A protector for protecting a cleaning hose inserted into an end of a generally cylindrical sewer pipe and withdrawn therefrom during cleaning with contact against an end of the sewer pipe includes a body having a generally cylindrical insert portion dimensioned to be received in the end of the sewer pipe and a flange portion. The flange has a radial width, relative to a central axis of the pipe, greater than a wall thickness of the pipe. A back surface of the flange portion is held against an end surface of the pipe, thereby retaining the protector in position to prevent the hose from scraping against the pipe end and being damaged. The protector is preferably permanently installed on the pipe.
