ABSTRACT:
The attachment device comprises a C-shaped profile fitting and a clamping strap, inserted therein, with an inset screw. The mutually facing strips of the fitting are thickened on the inside towards the slot. The strap grips behind this thickening. Thus the limbs of the fitting are prevented from spreading apart. In order to secure the strap against displacement along the profile, it has transverse webs which penetrate with an edge into the thickenings when a nut is tightened on the screw and thus produce a positive connection between the strap and the profile even in the longitudinal direction of the profile. The attachment is suitable, above all, for the underfloor attachment of appliances to rail vehicles.
