If a multiple branch of a shorter length is desired, branch lines can be dispensed with and corresponding ring parts removed and the remaining parts of the multiple branch connected to one another. If it is desired that some of the liquid lines run offset by 180 ° with respect to other lines, the connecting lines and the connecting parts can be connected offset by 180 ° in a simple manner. Under certain circumstances, offsets other than 180 ° can also be achieved.
