摘要

Fastening members pass through apertures (6) of a guide rail (1) side shank abutting the support wall (5), as adjacent to it with fastening members is provided a holder (8), twisted about the member centre axis w.r.t. the guide rail and securing the rail side shank in mounted state. All guide rails apertures are of elongated type and all fastening members are securable to the support wall prior to mounting the guide rail. Each holder is so shaped that it can pass through the aperture in one or more twist positions while in all other positions it blocks the passage through the aperture.
