PURPOSE: A pipe fixing tool is provided to reduce a session and costs by joining pipes having various diameters through changing the diameter of the pipe joining unit of an insert. CONSTITUTION: A pipe fixing tool(100) comprises an insert(110), a tightening ring(120), and a fixing cap(140). The insert comprises an insertion portion(111) and pipe joining portion(112). The insertion portion is inserted into an insertion hole of a pipe connection part(21). A pipe(10) is joined to the pipe joining portion. The tightening ring fastens the outer circumference of the pipe joined to the pipe joining portion, thereby fixing the pipe to the pipe joining portion. The tightening ring is elastically changed so that a diameter of the tightening ring is decreased by a cut portion(121). The fixing cap is thread-combined to the pipe connection part and fixes the insert to the pipe connection part and elastically changes the fastening ring.
