Abstract: A suction lance comprising at least one tube and a guide body made from an elastomer material axially displaceable on this tube is provided. The suction lance comprises a retaining section for a connecting body, a conical section axially adjoining the retaining section, the radially largest section whereof lies axially closer to the retaining section than the radially smallest section thereof, and a connecting body for the detachable connection of the suction lance to a removal opening of a container. The connecting body is fastened to the retaining section of the guide body, and the conical section of the guide body, by reason of its material, its radial size and the shape of its external contour, is designed to act in case of use as a sealing body in a removal opening of a container.
