The assembly has an elongate shield having an open proximal end, a distal end and a sidewall with an inside surface defining a cavity. There is an elongate aperture into the cavity from about the distal end to the 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 portion of the needle hub. The shield is movable about the hinge by an off-axis pivotal movement between 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 shield to hold it in the initial closed position. The cover is removable by a distal axial movement that also opens the shield, disengages the cover from the shield exposes at least the distal point of the needle.
