A needle safety device <；B>；40<；/B>； for an intravenous catheter apparatus that includes a base <；B>；42<；/B>； capable of receiving a needle <；B>；20<；/B>； between opposing jaws <；B>；48<；/B>； attached to the base and capable of being influenced by the needle <；B>；20<；/B>；. The jaws have a link <；B>；49<；/B>； connecting the jaws arranged a distance from the base <；B>；42<；/B>；. The jaws may move between an expanded position in which they interact with an obstruction within a wing housing of the intravenous catheter apparatus. The jaws <；B>；48<；/B>； permit relative movement of the needle <；B>；20<；/B>； with the base when expanded, close around a needle tip as it passes the jaws, and prevent relative movement of the needle <；B>；20<；/B>； with the base when the jaws are collapsed. The needle <；B>；20<；/B>； of the intravenous catheter apparatus may then be safely disposed with the needle tip within the needle safety device.
