The syringe is designed for medical use and has, attached to its cylindrical body (1), a needle-receiving device (3) in the shape of a Luer cone, for inserting a cannula. This needle receptacle (3) is sealed until use with a cap (2), such as a tip-cap. The sealing cap (2), together with the end of the needle receptacle (3), is enclosed by a detachable safety cap (4) secured by a safety ring (5). The sealing cap (2) is snapped and/or affixed firmly into the safety cap (4). The safety ring (5) is attached to the needle receptacle (3) by a holding ring (6), in such a way that the safety ring (5) surrounds and grips the holding ring (6) and the holding ring (6), when pushed into position over the needle receptacle (3), engages it securely. |
