Abstract: PROBLEM TO BE SOLVED: To facilitate the removal of an insulating wire protecting pipe or a protective pipe from overhead wiring by forming a driving tire which is rotated by driving force from the outside at the guide body middle part of a delta wing type joint split guide. SOLUTION: A horizontal wire pressing angle 1 is brought into contact with the upper surface of a wire 10, and a guide body 3 is fixed onto the wire 10 by a fastening tool 11. The cut line 8 of an insulating wire protecting pipe or a protective pipe 7 is then fitted in the front end of a boat form guide 2 by a tool and is guided to such a point as it engages with a driving tire 6. The driving tire 6 is rotated to pull the insulating wire protecting pipe or the protective pipe 7 into the guide body 3.  When the jointing part 12 of the insulating wire protecting pipe or the protective pipe 7 engages with a delta wing type joint split guide 5, it is expanded and contracted rapidly, so that the inside of the insulating wire protecting pipe or the protective pipe 7 is contracted to such a degree as to have an original diameter while the outside of the insulating wire protecting pipe or the protective pipe 7 is opening largely, therefore, the joint is removed automatically. It is thus possible to remove the insulating wire protecting pipe or the protective pipe continuously by simple work.
