A holder for multiple optical fibres, in which a detachable connection is created between the holder and the optical fibres by elastic engagement in a seating The holder includes a comb element with a receiving side facing the optical fibres and a base surface facing the cabin structural part. The comb element has an elongated shape and seatings arranged on the receiving side and extending transversely to the longitudinal direction. The seatings are separated from by fins, and the base surface is partly covered with double-sided adhesive strips. A cavity is formed between the base surface 7 and the cabin structural part for injecting a curable adhesive. Adhesive connections between the holder and the cabin structural part combine the immediate loading capability of a pressure-sensitive bond with the ageing resistance of a reactive adhesive.
