Abstract
Abstract Syringe for medical use of the disposable type provided with a hollow cap (40; 60; 60') that can be superimposed to the needle to protect it after carrying out the injection; the internal surface of the cap, close to its opening, and the external surface of the collar (44) for needle connection to the syringe have a substantially complementary shape. Close to the opening of the cap cavity, members 48, 61) are provided that firmly engage the collar (44) of the needle when it is forced into the cap cavity. Preferably, the cap comprises a support base (70, 71) to keep it in an upright position with the opening of cavity upwards when said cap is removed from the needle (46) and is laid on a support plane.
