A needle safety device includes a sleeve having proximal and distal portions separated by a radially-inwardly projecting ledge. A ring in the proximal portion is movable between a first position spaced from the ledge, and a second position adjacent to or abutting the ledge. A shield with at least one radially deformable tab receives the syringe and is movable in the sleeve between an initial position with the tab adjacent to or abutting the ledge, an injection position with the tab spaced from the ledge, and a protection position with the tab located distally from the ledge. The tab, during movement between initial and injection positions, deforms inwardly and traverses the inner surface of the ring, and during movement between injection and protection positions, translates with the ring from the first to the second position, and subsequently deforms inwardly and traverses the inner surface of the ring and the ledge.

A needle safety shieldfor use with a syringehaving a barrel, a needle and a plunger rod. The safety shieldhas a first tube. A second tubeis arranged for sliding movement within the first tube. A pinis connected to one of the first and second tubes. An activation ringhas a stop. A drive springbiases the activation ringin a proximal direction to place the stopin engagement with the pinto retain the first and second tubesin a retracted configuration. The movement of the plunger rodto engage the activation ringcompresses the drive spring, moving the activation ringdistally, and moving the stopout of engagement with the pin, allowing the drive springto move the first and second tubesinto an extended configuration.
