The invention relates to an outlet pipe assembly for a filling nozzle (14) for dispensing a fluid into a container. The outlet pipe assembly comprises an outlet pipe (16) having an inlet end (21) that can be connected to a housing of the filling nozzle (14) and an outlet end (22) opposite the inlet end (21), and a sealing unit (17) that encloses an outer side of the outlet pipe (16), which can be brought into sealing contact with an opening environment of the container after the outlet pipe (16) has been inserted into an opening (23) of the container, such that a return channel (41) for returning fluid vapours escaping from the opening (23) is formed between the sealing unit (17) and the outlet pipe (16). The outlet pipe assembly also has a valve device (34) connected to the outlet pipe (16) for closing the return channel (41) and a sensor device (35) for controlling the valve device (34). The sensor device (35) is designed to switch the valve device (34) into a closed position when a pressure threshold value is fallen below in the return channel (41). As a result of the arrangement of the valve unit on the outlet pipe, the latter can be replaced as a whole or can be used for retrofitting a filling nozzle.
