Abstract
Improved fitting for injection needles that is mainly characterized, in being made of a transparent thermoplastic material, with the particularity that the classic frustoconical axial hole is produced with smaller base diameter, smaller than the diameter of the smaller base of the truncated cone of the syringe, all in such a way that once the needle is inserted in the cone of the corresponding syringe, there is a free space between the lower end or base of the cone of the syringe and the smaller base of the frustoconical hole of the syringe the needle, thus creating a chamber through which the liquid is visible as it passes from the syringe to the needle and vice versa.
