Provided is a clamping device for temporarily connecting two ends of a large-pipe element with at least two connection devices and a rigid connection rod, with the connection devices being arranged at the ends of the connection rod. The clamping device is used to connect and secure the plate ends of large pipes and large-pipe elements. The clamping device is, unlike the known tack welds or auxiliary connectors (cleats), mobile, reusable, and versatile. It can be mounted quickly and securely on pipe elements of different diameters in order to reduce the load on the tack weld and, in the event of tack weld failure, take the place of it.
