Abstract: A catheter instrument and method for assembly extends in a proximodistal direction along a center axis (A). The catheter instrument comprises a catheter assembly having a catheter hub with a distal end, comprising a high pressure clip provided with an engagement socket, and a needle shielding device having a proximal end comprising a needle protection clip having a proximal engagement portion. The proximal engagement portion engages the socket when the catheter assembly and the needle shielding device are connected to each other.

Abstract: The present disclosure discloses a needle shielding device for a catheter instrument extending along a longitudinal axis A, comprising an inner part comprising an inner part track extending along said axis A, a middle part comprising a middle part track extending along the axis A, and an internal middle part engagement, an outer grip part, comprising a needle hub, holding a needle extending along the axis A, and grip part internal engagement. The grip part internal engagement is configured to slidingly engage the middle part track, and the middle part engagement is configured to slidingly engage the inner part track such that the inner part, the middle part and the grip part are telescopingly slidable in relation to one another.
