A medical handling which connects two implants arranged spatially separated from each other, by a flexible connecting line, along which a mechanical interface forms a plug-socket connection. The handling set comprises a tube and a mandrin which is internally guided therein and provides a mandrin tip, fixedly attached to a distal mandrin region which is a releasable first joint. In the joined state the handling set projects beyond the distal tube end. A first joining contour, which is part of a second joint, as well as an adapter element with a counter joining contour which is contoured counter to the first joint forms a second join, and a second joining contour contoured counter to the plug or socket of the mechanical interface which is part of a third joint.
