Abstract: A universal connection system for pipe connections provides a universal connection system for pipe ends with straight cut and/or miter cut as well as with a miter cut with radii made in one piece for straight, T-shaped, crossed as well as acute-angled and obtuse-angled pipe connections as well as for pipe ends with elbows, pipe bends, sections, hollow sections and plates with invisible connection elements. The system is also suitable for pipe systems for ducting cables and for carrying all types of gaseous and liquid media. The system includes clamping systems (2) or clamping systems (2) coupled with straight or hinge-shaped connection elements with axially and radially movable tie-in points. Threaded bolts, that (6) can be arranged centrally, straight, T-shaped and crossed and acute-angled and obtuse-angled connections of pipe sections (8) with one another or of pipe sections (8) with solid sections, elbows, pipe bends, plates and the like can be easily mounted and are invisible.
