Connection system for two structural component parts constructed as pipe or rod and/or nodal elements

Connection system for connection of two structural component parts containing connection ends having front recesses, axes and cylindrical outer surfaces, comprising:

• an articulated connection element serving for connecting said structural component parts in selected ones of a plurality of possible angular positions between said axes and having connection means determined for being anchored with the structural component parts and for being inserted into the connection ends thereof;
• and an angle element having a spherical surface and a through-passage receiving said connection element in said plurality of angular positions, said through passage having two ends ending at said spherical surface, and said angle element being mountable between said connection ends under a formation of joint faces with said spherical surface, wherein the connection ends are provided with concave curved contact surfaces for contacting said spherical surface in such a manner that said cylindrical outer surfaces open into said spherical surface substantially tangential when said structural component parts and said angle element are connected with each other by means of said connection element.
