Zero insertion force rivet device

A rivet device for fastening a set of parts which, when assembled together, include orifices having a common axis, and which present a total given thickness, said rivet device comprising:

• a member formed by a substantially tubular body having first and second ends;
• an annular collar projecting from said first end outwardly from said body substantially in a plane orthogonal to an axis of said body;
• and
• at least two locking elements formed in the body, each locking element being constituted by an elastically deformable strip cut out in said body and separated from said body by two cuts, said locking elements extending in a direction of the axis of the body, and having a first end secured to the first end of said body and a second end secured to the second end of said body, each strip having folds having two stable states, said folds being formed such that in an initial state said strip entirely projects into an inside of said body, and such that in a deformed state said strip is capable of projecting outside said body, a distance along the axis of said body between said collar and the projecting portions of said strips in the deformed position being substantially equal to the thickness of the set of parts to be assembled together as measured in a direction of the common axis of their orifices.
