The installation is used for cleaning conveyor pipes of a concrete distribution system consisting of a number of conveyor pipes and an end distribution hose. It operates with the aid of a cleaning ball pressed through the conveyor pipes which is caught at the end of the conveyor pipes by a pick-up device made like a pin. The pin (13) fitted on the outlet of the conveyor pipes (7) is connected with a swivel installation connecting the outlet conveyor pipe (7) and the end distribution hose (5) in such a way that during the swivelling away of the hose (5) the pin (13) is swivelled into the free cross section of the outlet conveyor pipe.
