The guard comprises an oblong flexible cylindrical body (5a) of dia. corresp. to the pipe internal dia. and longer than the protruding part. An outer support (11a) is provided for when the pipe end is bent over, so as to prevent kinking and keep a constant circular cross-section in the bending zone. The oblong body also has a fixing device (7) securing to the end and forming a plug. |
