Summary:A nozzle for an injection-moulding device comprising a torpedo-like insert (10) equipped with an axial duct (16) that communicates, on one side, with the duct (5) that supplies the melted plastic and, on the other side, with several ducts (17, 17´, 17", 17"'). The ducts are transversal to the axis of the insert and flow out onto the surface of the insert (10), and communicate with two counter spiral grooves (18) cut into the surface of the insert (10) that intertwine and form basso-rilievo figures (19) with a rhomboid shape.
