, 2, and a short pipe 6 for forming an edge is fitted onto the outer circumferential surface of the joint of the two pipes 1.2 with a sealing material 5 interposed therebetween. The sealing material 5 may be silicone resin or the like. The short tube 6 for forming the edge is, for example, made of a material that is harder and more elastic than the above-mentioned sealing material, and has a cylindrical shape with an inner diameter slightly larger than the outer diameter of the tubes 1 and 2. The edge is provided with a collar 7 that projects inward. Further, a projection 8 for preventing slippage is provided on the inner surface of the short pipe 6 for forming an edge, and when the short pipe 6 for forming an edge is fitted into the pipe 1.2, the projection 8 for preventing slipping fits into the recess 3, and the pipe 1.2 is fitted into the recess 3. This is an example of one that is designed to prevent it from being pulled out. Fit the joining end of the tube 1.2 into contact with the collar 7 of this short edge forming tube 6, and then abut both edge forming short tubes 6 and apply adhesive 9 to their outer surfaces. The cylindrical body 10 is fitted through the tube to connect both of the edge forming short tubes 6.
