A dispensing device for flowing substances is attachable to a container and comprises an outlet tube of flexible material adapted to be dependent from the container and at the bottom terminated by an outlet opening. The dispensing device comprises valve arrangement for controlling flow of the substance through the device. Furthermore, the dispensing device comprises an intermediate piece comprising a first portion for releasably securing the outlet tube to the intermediate piece and a second portion for releasably securing the intermediate piece to communicate with a discharge opening of the container. The intermediate piece comprises a valve seat for restricting movement upwardly of the valve arrangement on squeezing of the flexible outlet tube.
