ABSTRACT:
A method for assembling at least two elements by a crimping rivet including a head and a stem, and an associated fitting tool including a traction rod. The method includes the following successive steps. A securing step that secures a part of the stem of the rivet by die-stamping on a corresponding part of the traction rod of the fitting tool inserted inside the stem of the rivet. An inserting step that inserts the rivet in corresponding holes of the elements to be assembled. A crimping step that crimps the rivet by the fitting tool. A separating step that separates the fitting tool by radial deformation of the part of the stem on which die-stamping was applied.
