Abstract:
1. A fastener, for connecting a first component having a first hole to a second component having a second hole, comprising: a cage which is fitted at its end with a radial flange and further a cross-sectionally rectangular or square shank segment, said shank segment being adapted for insertion into the second hole of the second component, said flange being adapted to rest against a side of the second component, a nut that is at least partly axially received in the cage and that is rotatable from a first rotational position in the cage into a second rotational position and moreover is fitted with an axial borehole adapted to receive an affixation screw and also comprises at its outside, diametrically opposite wing elements, where, upon rotation of said nut from the first rotational position into the second rotational position, said wing elements will be pulled, on account of the affixation screw's rotation in the nut, against the other side of the second component, a head of said affixation screw are adapted to rest against the first component and compress the first component against the flange, wherein the cage and nut are made of molded plastic, the second hole is adapted to be square or rectangular and the wing elements of the nut are situated in the first rotational position within a contour of the cage and in the second rotational position, will radially project beyond the cage contour against a stop of the cage; and wherein the nut further comprises a cylindrical segment between the wing elements, said cylindrical segment comprising at its end facing the flange an annular collar and the cylindrical segment being insertable into the cage, where the collar cooperates with a peripheral inner shoulder of the cage, as a result of which the nut is rotatably supported between the rotational positions.
