Header tube fixture

PROBLEM TO BE SOLVED: To obtain a header pipe fixture capable of easily fixing a header pipe to a base plate even if a heat insulating material and the like is not wound around the header pipe.SOLUTION: When a header pipe 30 is fixed to a base plate 22 by using a header pipe fixture 10, a worker presses the header pipe fixture 10 toward the base plate 22 so as to lock a locking claw 16B to a locking hole 28 of the base plate 22. An elastic deforming part 14 is elastically deformed, and the locking claw 16B is inserted in the locking hole 28 and locked to the locking hole 28. Therefore, the elastic deforming part 14 is elastically deformed, so that the header pipe 30 can be easily fixed to the base pate 22 even if a heat insulating material and the like is not wound around the header pipe 30.
