The invention relates to the technical field of pipeline fixation and discloses a pipeline clamp. The pipeline clamp comprises a fixed part which is of a semi-encircling structure and also comprises a first spring sheet with a vertex angle, wherein the first spring sheet is fixedly connected with the fixed part inside the fixed part; the vertex angle is a non-fixation point; one end of the first spring sheet is connected with a movable part; the movable part is connected with the fixed part to form a full-encircling structure; the first spring sheet is provided with a first position; two sides of the first spring sheet form pipeline fixing spaces; under the lateral pressure effect, the first spring sheet is close to the fixed part and moves to a second position; and two sides of the first spring sheet respectively form pipeline fixing spaces or only one side of the first spring sheet forms a pipeline fixing space. The pipeline clamp is strong in universality and convenient to use. The invention also discloses a pipeline fixing device, which comprises a top plate and a bottom plate which are arranged in parallel, wherein two groups of pipeline clamps are arranged between the top plate and the bottom plate; openings of the fixed parts of the two groups of pipeline clamps respectively face two directions opposite to and parallel with the top plate, so pipelines are conveniently arranged symmetrically and fixed simultaneously.
