Zusammenfassung:	A tool for lowering, alternatively later retrieval, of a pipeline end which is provided with a connecting part designed for mating with and connection to a first connecting part on the seabed is shown. The tool is so arranged that the tool can be brought to the surface again for reuse. The tool comprises a central lifting frame, a guiding part forming an extension of the lifting frame and a lifting yoke, which tool includes gripping mechanisms which, in one situation, are actuatable to partly circumscribe and retain the pipeline end, and, in a second situation, the gripping mechanisms are releasable to release the pipeline end from the lifting frame.
