Claim:
A needle stick guard for an anti-needle-stick puncturing kit for installing a catheter by the Seldinger method, comprising: a rocker having a bearing for its rotation about an axis, and an external tip for locking the needle stick guard together with a base of another element of the puncturing kit; a body comprising: a proximal hole and a distal hole for inserting a tube of a needle and inserting a spiral guide between the proximal and distal holes; a slot for receiving the rocker; and a housing on the periphery of the slot for receiving the bearing of the rocker; characterized in that the rocker has three positions about its axis of rotation: a locking position wherein the external tip locks the needle stick guard together with the base of the other element of the puncturing kit; an unlocking position wherein the external tip releases the needle stick guard from the other element of the puncturing kit; and a protection position wherein the sharp end of the needle is trapped by the body of the rocker; and in that the rocker has a spur within the body for controlling the position of the rocker with respect to an outer diameter of the tube of the needle and/or of the spiral guide; the locking position being obtained when the spur is resting on the tube of the needle; the unlocking position being obtained when the spur is resting on the spiral guide; and the protection position being obtained when the spur is resting neither on the tube of the nor on the spiral guide.
