Abstract

PROBLEM TO BE SOLVED: To maintain connected pipes linearly by arranging a block body between a drop part and a ring body in the substantially central part of a short round pipe which can be inserted into a pair of round pipes to be connected and is provided with engaging notches, which are engaged with engaging rods arranged inside the round pipes closely to theirs end parts, in both ends and allowing the block body to freely move in the circumferential direction. SOLUTION: Insertion of one side of a short round pipe 4 is carried out until a ring body 5 is butted to one end of one round pipe 1 to be connected, and insertion of the other side of the short round pipe 4 is carried out until the ring body 5 is butted to one end of the other round pipe 2, and then, engaging rods 1a, 2a of the round piper 1, 2 are engaged in L-shaped engaging notches 3 in both ends of the short round pipe 4. In addition, a bolt 8 screwed into a dcrew hole 7a in a block body 7 is turned so as to be fastened, and the block body 7 is moved in the circumference direction of the ring body 5 between a drop part 6 and the ring body 5 so as to be brought into tight contact with the inside faces of the round pipes 1, 2. In this way, the round pipes 1, 2 connected together are prevented from pluy, and very firm connection can be accomplished.
