Method for separable connection and fixation of two circular cylindrical pipe ends, system for connection of two pipe ends with the same external diameters and the same material thickness and use of such a system

A system for joining two pipe ends having the same outside diameters and the same wall thicknesses in a mutually non-rotatable extension of each other with coinciding central axes, comprising:

• a joint sleeve having a cylindrical pipe section and configured for receipt and joining of each of the pipe ends, wherein movements in the radial direction are prevented by frictional engagement between the joint sleeve and each of the pipe ends;
• a sprung detent configured for deformation during the insertion of each pipe end and configured to prevent pulling out of the pipe ends from the joint sleeve;
• and
• toothings configured to prevent mutual rotation about the central axis of the pipe ends, wherein each of the toothings comprises at least one retracted radial angular section of each pipe end, which in the longitudinal direction is retracted from a foremost edge of each respective pipe end;
• wherein the retracted radial annular section of each pipe end receives a non-retracted radial angular section of the another pipe end when the toothings of the pipe ends engage in the joint sleeve;
• wherein the retracted radial angular section of one pipe end is longer in the axial direction than the retracted radial angular section of the other pipe end, so that when the pipe ends are engaged in the joint sleeve at least one gap is formed where the pipe ends are not in contact with each other;
• and
• wherein each of the at least one gaps is filed by a protrusion inside the joint sleeve when the pipe ends are joined therein, wherein the protrusion has the same inside diameter as the inside diameter of the two pipe ends.
