Claim:
1. A plastic needle tip shielding device comprising: a body with a rear side, a front side, an outer surface connecting said rear side and said front side, and a hole extending from said rear side to said front side, said outer surface having an outer diameter configured to engage an inner surface of a catheter hub; a resilient arm connected to and extending from an attachment point on said front side of said body and with said front side spanning said outer diameter of said outer surface, said attachment point being located between said outer surface and said hole; at least one protuberance on said outer surface; and an elevation about said hole; wherein said resilient arm has a resting state, from which it may be forced to yield free passage through said hole in an axial direction of said body, said resilient arm being adapted for clamping a needle tip of a hollow needle extending through said hole in a direction from said rear side to said front side, when said resilient arm is in said resting state; wherein any straight imaginary line extending longitudinally through said hole in the axial direction of said body coincides with said resilient arm, when said resilient arm is in said resting state; and wherein said plastic needle tip shielding device includes a thermoplastic polymer.
