Claims

[Scope of utility model registration request]

In a pipe connecting fitting that is inserted into the pipes to be connected and connects the pipes in a substantially straight line, the outer rod and the inner rod, each having a substantially C-shaped side surface, are arranged so that their openings face each other, and the fitting is inserted into a predetermined pipe. A press-fitting body is formed, a fixing ring is externally fitted approximately at the longitudinal center of the press-fitting body, and a tightening bolt inserted from the outside of the fixed ring to the inside of the press-fitting body is pressed against the inner surface of the pipe material by expanding the press-fitting body. A pin is screwed into a pressing nut disposed inside the press-fitting body, and a pin is protrudingly provided on the surface of the expanding press-fitting body to be inserted and engaged into a locking hole drilled at the end of each of the pipe materials to be connected. A pipe material connection fitting with a retaining pin.
