In packing machines which have a filling pipe with two or more ducts, a rinsing of the filling pipe with cleaning fluid may lead to only one duct being properly cleaned. In order to prevent this, an arrangement is provided on packing machines which have a coupling part provided with valves with passages which are coupled in series with respective ducts in the filling pipe. The valve is adapted so that it is acted on towards the closed position by the cleaning fluid flowing past and thus limits the flow through the one duct so that the other duct too is assured of an adequate flow for effective cleaning.
