A threaded connection for tubing joints having a threaded part and a matching part fixedly connected with the tube, which embraces the tube externally and rests with an inner surface having grooves at the outer surface of the tube, wherein the fixed connection between the matching part and the tube is produced by rolling material of the tube into the grooves, the matching part 2 having at least one groove 7, 8 which is conducted in a threaded shape manner, so as to prevent failure of the tubing joint by crack formation.


A tube connection, comprising a threaded part and a matching part fixedly connected with a tube, which matching part embraces the tube externally and has an inner surface that faces the tube with two sets of thread-shaped grooves into which the tube is rolled so as to fixedly connect the tube and the matching part, the matching part further having smooth cylindrical inner surfaces arranged on both sides of said grooves, which smooth surfaces have a common internal diameter and rest at an outer surface of the tube, the thread-shaped grooves having an exte...
