A cable marker includes a housing which has an accommodating opening to accommodate a label to mark a cable, a cover to close the accommodating opening in a closed position of the cable marker, and a film hinge integrally connecting the housing to the cover such that in an open position, in which the cover does not close the accommodating opening, the cover can be pivoted in relation to the housing along a pivoting plane. The film hinge has a first base portion connecting the film hinge to the housing, a second base portion connecting the film hinge to the cover, and a connecting portion arranged between the first base portion and the second base portion. The connecting portion has a width that is reduced in comparison with at least one of the base portions as viewed in a direction perpendicular to the pivoting plane.
