• the dimensions of the holding device 101 and the through opening 310 were matched to one another such that the holding device 101 preferably rests in a plurality of areas in transition fit with the side walls of the passage opening 310. If, as in the present case, the securing structure 130 projects beyond the passage opening 310, the insertion of the holding device 101 into the passage opening 310 requires a combined translational and rotational movement.
