  • the invention further relates to an arrangement having a spacer, a separating device and a mounting rail.
  • mounting rails which can also be referred to as top-hat rails or profile rails, are used to fasten electrical add-on parts, for example in distribution boxes.
  • the mounting rails are usually available by the meter or with specified lengths, for example with a standard length of 2 meters, and have openings that are evenly or differently spaced from one another, often elongated holes, which extend along an expansion direction of the mounting rail in the material of the mounting rail, for fastening the mounting rail , for example using suitable screws, to a surface.
  • Cutting or cutting or shortening the mounting rails to the desired size is usually done by a worker or a fitter before installing and equipping the mounting rail.
  • Separating devices suitable for cutting mounting rails to length are known from the prior art.
  • US 5,934,166 describes a cutting device designed as a cutting device, which is suitable for cutting a mounting rail to a desired size.

  • a further advantageous development of the invention provides that at least one of the clamping legs is set up and designed in such a way that a free end of the clamping leg is elastically displaceable to a free end of the further clamping leg. In this way, it is possible to achieve a clamping effect by at least one of the clamping legs being elastically deflectable and allowing its free end to be displaced.
  • the further clamping leg can, for example, be designed to be rigid, so that the clamping force is generated by the one clamping leg as soon as the mounting rail is arranged between the two clamping legs.

  • the invention therefore provides for the clamping legs to be set up and designed in such a way that they allow a spacer according to the invention to be snapped onto a mounting rail.
  • a further increase in the holding effect is made possible by a further development of the invention in that the clamping legs are designed and arranged on the base body in such a way that at least one of their inner surfaces engages behind the mounting rail at least in sections.
