A method for crimping an insert to be clinched in a support by means of a placing apparatus having an anvil, in an area where the support comprises superposed first and second panels at a distance from one another, wherein the shank is inserted axially in the support and the anvil is brought up against the distal end of the shank, and the second section is then axially compressed against the anvil to create a securing edge, axial compression of the second section then being continued to create a crimping rim delineating an anchoring groove, in combination with the securing edge, surrounding the second panel, axial compression of the second section then being continued to bring about clamping of the support between the securing head and the securing edge in conjunction with clamping of the second panel between the securing edge and the crimping rim.
