The holder section is connected with the sealing skin of the tunnel and, if necessary, sealed to the upper part of conveying track (9) or similar. The holder section is fixed to a section of the tubbing via an embedded section (6) and connected with the sealing skin. The embedded section of the holder section may be tapered in cross section to the sealing skin. The holder section may have a connection area (8) that may overlap the surface (7) of the tubbing.
