摘要

The cross-bar (1) has two identical seats (2) for receiving respective rails (R1, R2). Each seat is provided to accommodate adjacent ends of two consecutive rails that are joined together by clamping plates to tighten opposite sides of the ends of the rails and to ensure stable fixing of an interior of each seat. The clamping plates of the rails exhibit a metal structure and are provided in the interior of each seat. Two mutually opposite pairs of vertical built-in threaded blocks receive screws for fixing of plates. A groove is located between two halves of each seat.
