Abstract
An imperdible needle perfected, by the fact that the steel wire, V-bent in the known way, is provided with a capsule of natural or synthetic plastic material fused on a small bend of the fixed arm of the needle which capsule is endowed internally of an irregular spiral shaped labyrinth thanks to which the mobile arm of said needle is retained inside it in unsurpassed safety conditions since for the opening of said needle to occur it is necessary that said mobile bruzo continue a zigzag path in order to pass it through an inner slit and through an opening through which said labyrinth communicates with the outside, completing the advantages of the new needle with a small metal sheath which partially surrounds in the form of clamp the ring or winding that constitutes the expansion spring, covering the sector in which the wires that form the two turns that they juxtaposed.
