Abstract: An adaptor for drawing a liquid from a container that is sealed with a plug or for filling the container. The container being sealed with a plug that is attached by a flange cap. At least one mandrel on the front end of the adaptor for penetrating the plug, a connecting part with an inner cone at the rear end for hooking up medical devices, and a flat gripping element in the intermediate area for facilitating the adaptation process. A funnel that is open toward the rear end is arranged on the connecting part of the adaptor. In addition, an elastic centering and gripping part is arranged toward the front end of the adaptor on the gripping element. The inner contour of the centering and gripping part approximately corresponds, at least in terms of area, to the outer contour of the flange cap that attaches the plug to the injection container. The inner contour also has locking elements that engage behind the flange cap at least in sections.
