1. A lightweight-construction fastener, comprising:
a one-piece clip body formed of plastic and having a
basic form of a clamp
with two opposite legs extending in a longitudinal direction
and a web which connects two opposite leg ends;
a receiving space for a plate-shaped component between the legs which is delimited on one side by the web;
a clip nut
which has a nut base configured to be substantially plate-shaped with a flat, planar base surface facing toward an inside of the clamp;
a main body built up on the nut base having a covering surface as well as a multiplicity of side walls which extend between nut base and covering surface;
the main body has a substantially polygonal cross-section parallel to the nut base;
a central middle opening extends through the nut base, the main body and the covering surface;
a first leg of the clip body has a cage comprised of multiple wall elements in which the clip nut is mounted to be movable in a floating manner;
the cage has at least two holding openings,
the second leg toward the inside of the clamp is configured as a tongue-shaped, flat bearing surface, and
the first leg in a region of the cage and the second leg in a region of the tongue have in each case an opening which are flush with the central middle opening of the clip nut arranged in the cage;
the first leg is configured so that the base surface of the clip nut points toward the inside of the clamp and is formed as a bearing surface for direct contact with the plate-shaped component; and
the main body of the clip nut has at least two pin-shaped lugs which engage in the openings of the wall elements of the cage.
