ABSTRACT:
For forming a fluid tight removable connection between a high pressure tube and a sleeve, an olive is sealingly secured to an end portion of the tube by electromagnetic forming. Then a nut is threaded on the sleeve for deforming the olive and forcing it sealingly against an internal face of the sleeve. When the olive is at least partially of electrically conducting material, it is shrunk onto the tube by magnetoforming after a removable forming die has been inserted into the tube.
