A spring clip needle tip shielding device for arrangement in a catheter hub of an intravenous catheter assembly is provided. The spring clip needle tip shielding device comprises a base plate with a hole extending therethrough and at least one resilient arm extending at an attachment point at said base plate. The at least one resilient arm has a resting state, from which it may be urged to yield free passage through said hole in an axial direction of said base plate in a tension state, said at least one resilient arm being adapted for clamping a needle tip of a needle extending through said hole when said resilient arm is in said resting state. Any straight imaginary line extending longitudinally through said hole in the axial direction of said base plate coincides with said at least one resilient arm when said resilient arm is in said resting state of said body. The spring clip needle tip shielding device is of a rigid material, and at least a part thereof is coated with a solid lubricant. A catheter assembly including such shielding device is also provided.
