The invention relates to a pipeline fixing device, in particular to a bifurcated pipeline fixing device, which is used for fixing a bifurcated pipeline and can be used for ensuring the trend of each branch of the bifurcated pipeline. The device comprises a base and at least two buckles, wherein the base comprises at least two base support parts; the base support parts comprise connecting ends and buckling ends; the connecting ends of the base support parts are connected together; the base support parts are positioned on the same plane; an included angle between adjacent base support parts is greater than 0 degree; the buckles are arranged at the buckling ends of the base support parts respectively, and are used for buckling bifurcated pipeline branches carried on the base support parts. According to the bifurcated pipeline fixing device provided by the invention, a special structure in which the base is matched with the buckles is adopted, so that fixation of the bifurcated pipeline can be realized, and the trends of the branches of the bifurcated pipeline are effectively kept.
