In an indicating instrument, the measuring mechanism (1) has ears (6, 7) protruding outwardly, which are accommodated by pockets (8, 9) at the rear of a front body (2), constructed as an optical waveguide, of the indicating instrument after rotation of the front body (2). Detents (16, 17) hold the front body (2) in the end position in a predetermined angular position on the measuring mechanism. <IMAGE>
