An arrangement for a darkening device for a vehicle roof having a tension bow and a coupling, said coupling including at least one coupling recess and being coupled to the tension bow at an elongate end thereof. The arrangement has a drive cable and a cable attachment which includes at least one coupling recess and which is coupled thereto at an elongate end of the drive cable. Moreover, the arrangement may have at least one coupling pin which extends in each case into the coupling recess of the coupling and into the coupling recess of the cable attachment and connects the coupling to the cable attachment and couples the tension bow to the drive cable, so that the tension bow can be moved in a predefined manner by the drive cable.
