The safety connector (9) for a hollow needle (10) consists of a supporting sleeve (11), a protective cylinder (12), and a large diameter with proximal cylinder (12d) and a smaller diameter distal cylinder (12e), both of which have impermeable side walls. The supporting sleeve has a thrust collar (11a) that goes inside the proximal cylinder with a clearance and fits against an intermediate collar (12f) connecting the two cylinders. In addition, the proximal cylinder has locking tongues (12i, 12j) to hold the collar in place and prevent the withdrawal of the needle from the protective cylinder. |
