ABSTRACT:
A fitting for holding and connecting steel pipes comprising: a holder and a coupler which are axially supported with each other at one end with a pin, a bolt which is inserted into a through hole provided at the other end of the coupler, and a cap nut which is provided inside the other end of the holder and into which the bolt is tightened, thereby holding a steel pipe. It is desirable for the cap nut to be fixed to the holder or for the through hole to be an unloaded hole. By so arranging, the steel pipe does not slide off from the tightening fitting, and in case of damage to the bolt, only the damaged bolt may be simply replaced with a new one, thereby making it possible to use the device for a long period of time. Moreover, since the screw portion of the bolt does not protrude, the clothes or body of the worker or passing person are not caught by a projecting end of the device so as to cause the clothes to be ripped or the body to be hurt.
