A needle assembly includes an elongate needle, a needle hub with an axial bo re therethrough to receive and hold the needle projecting axially, the needle h ub further is releasably mountable on a fluid handling device. The assembly has an elongat e shield having an open proximal end, a distal end and a sidewall with an inside surface def ining a cavity. There is an elongate aperture into the cavity from about the distal end to t he proximal end. The assembly has a hinge that includes a mount for retaining the shield onto the hub, the mount has an opening therein that is sized and shaped to receive at least a portio n of the needle hub. The shield is movable about the hinge by an off-axis pivotal movement betwee n an initial closed position, an open position and a latched position. The assembly has a removable cover that is disposed over the elongate aperture in the shield and engaging the s hield to hold it in the initial closed position. The cover is removable by a distal axial movement t hat also opens the shield, disengages the cover from the shield exposes at least the distal poi nt of the needle. There is a latch for latching the shield to the mount when the shield is in the latched position.
