In order to simply attach an optical fiber in a wall, the end porton of the fiber is enclosed by a tubular envelope. The envelope is accommodated in a holder which projects through an opening in the wall. The holder is rotatable about its longitudinal axis. The outer cylinder surface of the holder is provided with a circumferential groove. In two diametrically opposed portions, the depth of this circumferential groove is greater than the thickness of the wall of the holder so that two elongate openings are formed in the wall of the holder. The outer surface of the tubular envelope is also provided with a circumferential groove whose axial position coincides with that of the circumferential groove in the holder. A U-shaped spring is attached to the wall so that its legs are situated in the circumferential groove in the holder at the area of the elongate openings. The spring force presses the legs through these openings into the circumferential groove in the envelope so that the envelope is retained in the holder.
