Abstract

A catheter tube comprises one end (7) which is turned back to cover and trap a ring (5) fitted around the exterior of the tube. Such a tube can be made by forming an annular cup- shaped space by means of a mould and mandrel (2), sliding said one end of a tube down the mandrel and positioning a ring around the exterior of the tube. By softening the tube using heat and sliding the tube down the mandrel, the end of the tube is constrained to turn back and cover the ring. Pushing of the ring further within the turned back end of the tube causes crushing of the ring and the trapping of same by the turned back end of the tube. <IMAGE>
