Tack-rivet, of the type which, being of plastic material, incorporates expansion grooves and gripping projections, characterized essentially because the rear end of the body of the rivet-rivet carries a flexible tongue inclined towards the inside of its through-hole, which, before the action of a tool, it is capable of adopting a transverse position and anchored in an extreme diametral recess of the body itself, maintaining a conicity in the outer walls of the same adjuvants in the achievement of a wedge effect on the pieces to be joined, thereby effecting the function of a rivet at the same time.
