The tube (1) includes a connector (9) with a dispensing duct (13) which connects a dispensing opening (11) to a reservoir (3). For the dosed dispensing of a liquid from the reservoir (3) through the dispensing opening (11), a throttle insert (31) is inserted into a distal section (9b) of the connector (9) and is connected in form-fitting fashion to the connector (9). The connection of the throttle insert (31) to the connector (9) is preferably realized by a radial pressing action. The throttle insert (31) is preferably of dome-like form and delimits at least one primary throttle duct (47) which forms in the dispensing duct a constriction which limits the volume flow of the liquid from the reservoir (3) to the dispensing opening (11).
