Abstract: An assembly having a puncturing device and a receiving device is provided. The puncturing device has a puncturing element and a blocking element. The puncturing element is joined to a flexible tube and provided with a needle-shaped part. The needle-shaped part has a portion whose cross-section has at least one part set back in relation to a circle circumscribing the cross-section. The receiving device is joined to a sealed container and has a central longitudinal channel which is intended to receive, in a leak-proof manner, the needle-shaped part of the puncturing device. The channel has a portion with a cross-section complementing the portion of the needle-shaped part and a portion intended to cooperate with the blocking element of the puncturing device to form, when the puncturing device is situated in the final position in the receiving device, a leak-proof connection bringing the inside of the container into communication with the feed tube.
