A mounting fixture for mounting a sensor housing to a mounting surface includes: a clamp jaw having a first part and a second part, the first part and the second part of the clamp jaw each including a polygonal recess and being attachable to each other such that a recess of the first part of the clamp jaw and a recess of the second part of the clamp jaw together form an essentially hexagonal recess. The first part and the second part of the clamp jaw are attachable to each other by at least one fastening element so as to fixate the sensor housing in the essentially hexagonal recess. At least one of the first part and second part of the clamp jaw includes a mounting element for mounting the mounting fixture to the mounting surface.
