Cross-bar comprises fastening parts, which create screw-nut connections, and spacing bushes with end surfaces. Each spacing bush has length equal to distance between opposite sheets, which create the head and the tail. The body is provided with through orifices for fastening parts receiving. The fastening parts connect the sheets together so that cavity is defined in-between. Body is located in the cavity. Body thickness is less than that of the cavity. Spacing bushes are arranged in the cavities and are partly inserted in through orifices so that the spacing bushes are coaxial to fastening parts.
