A covering rosette (16) for a concealed sanitary fitting (10) comprises a covering hood (18) and a rosette support (20) which supports the covering hood. The covering hood (18) and the rosette support (20) comprise a clip mechanism (32, 46) configured such that the covering hood (18) can be mounted to the rosette support (20) while allowing a rotation around a central axis (28). In order to better adjust and fix a desired rotational alignment of the covering hood (18), the covering hood (18) and the rosette support (20) comprise a cam mechanism (40, 60) having a cam curve (60) and a cam follower (40), wherein the cam curve (60) is arranged on one of the covering hood (18) or the rosette support (20) and the cam follower (40) is arranged on the respective other of the covering hood (18) or the rosette support (20). The cam mechanism (40, 60) further is configured such that it sets an angular relation between the covering hood (18) and the rosette support (20) and that this angular relation can be changed by moving the cam curve (60).
