Furthermore, the invention relates to a device for dividing regions. To this end, a first mounting device (23 to 28) which can be mounted on the holding device (2, 3) and a second mounting device (23 to 28) which can be mounted on the holding device (2, 3) are used. Furthermore, a mounting element (35) is provided which can be mounted on the first mounting device (23 to 28) and has a receptacle (36), in which a dividing wall (1) can be received in a non-clamping manner.
