A disposable safety guard for syringe needles and the like, the safety guard being adapted to laterally receive the tip of a needle in an elongated interior chamber within a body member. The interior encloses a high frictional surfaced gripping device which receives the syringe needle in a lateral direction and prevents the needle from being removed therefrom, after it is secured therein. In a preferred embodiment, the gripping mechanism comprises a rectangular shaped plastic component having two planar members joined by a thinned or living hinge permitting the component to be folded in half so that it may conform to the shape of the interior of the body member and close upon the needle. In that preferred embodiment of the invention, a series of ridges on the folded interior surface of the gripper component increases the frictional engagement with the syringe needle. The gripper component has a pair of lips designed to engage a plurality of ratchet teeth in the interior walls of the body member chamber. The lips prevent the gripper from moving in a vertically upward direction within the interior and thus cooperate with the ratchet teeth in the interior of the body member to form a one way ratcheting effect. The ralationship between the lips and the ratchet teeth creates a leverage effect much like a nut cracker to firmly grasp and retain a needle of virtually any standard size.
