The suction tube (2) is connected to a collector and is placed against the mother's breast. The outward-opening funnel-shaped fitment (2.2) has an elastic funnel-shaped insert spaced increasingly apart from outside inwards from the inside of the fitment and placed on the outer rim of the fitment. The insert has an inner part (1.3) opening towards the collector and protruding into a tubular transition piece (2.3) positioned between the fitment and the collector. |
