Abstract: The disclosure specifies a fixing device for a current sensor, which fixing device comprises a holding element which is shaped in the manner of a U and a surface part which is connected to the free end of a limb of the holding element, with the surface part being arranged substantially perpendicular to the connected limb and extending away from the opening in the holding element. The fixing device also comprises a retaining element which is connected to the surface part and is shaped in the manner of a C, with the orientation of the opening in the retaining element corresponding substantially to the orientation of the opening in the holding element. By means of the fixing device for a current sensor, mounting can be simplified, carried out more quickly and performed in a manner which is less susceptible to faults.
