The present invention relates to an improved pipe fixing device for a construction machine, wherein a hydraulic hose that is connected to a side of a hydraulic cylinder of a work apparatus that has a boom of an upper swivel body of the construction machine, is plumbed and assembled to be detachable in phases from an upper and a lower part of a clamp, thereby fixing the movement of the hydraulic hose so to be structurally sound and thereby reducing the required manpower. The pipe fixing device comprises: a hose clamp comprising a pair of fixing parts that are attached to the side of an upper swivel body, a first connection part supporting at pre-determined intervals a plurality of first array hoses that are formed extending in-between the pair of fixing parts and that arrive from a lower part, and a second connection part supporting at pre-determined intervals a plurality of second array hoses; a guide that is coupled to the hose clamp so as to restrict the movement of the plurality of first array hoses; and a
