Abstract: A safety guard (10) for a needle has a slider (22) for slideably encasing the needle; a moveably traveler (34) that slides over and with the slider and is in sliding engagement with and within a housing (14). A resilient member (80) within the housing biases the slider distally to cover the needle. Radial recesses (26a, 26b) on the outer surface of the slider are engaged by cantilevered snaps (38) at the distal end of the traveller. Once the snaps are engaged they are prevented from moving proximally with respect to the slider, but can move distally from one set of recesses (26a) to another (26b).
