The device comprises at least a carrier (1) with a flat surface, in which centering grooves (5) are provided for the play-free take-up of an end section (13) of a light-conducting fibre (3) from which its protective cover (11) has been removed. The length of the centering groove (5) is at most equal to five times the diameter of the light-conducting fiber (3) without protective cover (11) and in the line with the centering groove a supporting groove (7) linking up with the centering groove is provided, the width of which is between 5 and 10 mu m greater than that of the centering groove. The supporting groove (7) serves to take up with play a second section (15) of the fibre (3) linking up with the end section (13) and from which the protective cover has likewise been removed. Thanks to the short length of the centering groove (5) temperature changes have no significant effect on the position of the end section (13) in spite of the different coefficients of expansion of the carrier (1) and the fibre (3).
