A fastening piece for attaching accessory parts, such as luggage carriers and side props, to double-tube sections of two-wheeled vehicle frames contains a central piece with a cross hole for receiving a fastening screw and two flanges which extend from the central piece and rest on the frame tubes. In order, along with better utilisation of material, to achieve better self-securing properties of the fastening piece, the flanges, while forming two respective outer faces have a mutually identical triangular form in the projection onto a plane parallel to the axis of the cross hole, facing towards the central piece with their base. The flanges can be elastically deformed in the direction parallel to the axis of the cross hole.
