It is possible and In addition to good operability, it is locked by the locking projections, and it is surely fixed. After the pipe is fixed to the pipe puller, the locking projection does not come out of the locking hole unless the bolt is turned, and the pipe is connected firmly. In addition to being able to provide a highly secure scaffolding frame while maintaining strength as a temporary scaffolding frame for a fierce workplace at a construction site, it is possible to provide a robust pipe connector with a simple configuration at low cost. It can be mass-produced and produced. Brief explanation of drawings

• BEST MODE FOR CARRYING OUT THE INVENTION In order to explain the present invention in more detail, embodiments will be described below based on the attached drawings.
• the outer peripheral short pipe 11 is fixed substantially at the center of the connecting pipe 1 made of iron or steel, and the nut portion 16 is provided so as to pass through the connecting pipe 1 and the outer peripheral short pipe 11.
• the bolt 10 is screwed into the nut 16 from the external force of the connecting pipe 1 and the outer peripheral short pipe 11.
• the tip of the bolt 10 is inserted into a guide tube 14 provided in the concave side of a support 2 having a channel-shaped cross section provided in the connection tube 1.
• locking projections 7, 8 are formed on the opposite side of the surface on which the bolt 10 abuts. are doing .
• the locking projections 7 and 8 are inserted into through holes 3 and 4 formed in the connection pipe 1, and the tips thereof can enter and exit through the through holes 3 and 4.
• a recess 15 is formed on the back side of the guide tube 14 of the support 2 on the side where the locking projections 7 and 8 of the support 2 are formed, and both ends of the plate-like viscous material 9 guided in the recess 15 are formed. Is brought into contact with the inner surface of the connection pipe 1, and the support 2 is pressed against the tip of the bolt 10 by its elastic force.
• Holes 5 and 6 are:
• notches 17, 18, 19, and 20 are provided to engage with protrusions provided on the conventional pipe.
• the configuration in which the locking projections 7, 8 protrude in the screwing direction is the best embodiment. It was shown. That is, when the locking projections 7 and 8 are inserted into the locking holes 5 and 6 and the locking is performed, even if a force for pushing the locking projections 7 and 8 from the outside is applied, the locking projections 7 and 8 are supported. This is because the tip of the bolt 10 is on the back surface of the body 2 and the support 2 is not displaced.
• a temporary scaffold frame is constructed by sequentially connecting pipes for constructing a temporary scaffold frame at a construction site in connection with connection of various pipes using the same.
• the pipe connector can be easily manufactured.
