The needle hub includes a fin formed with a latch. A safety shield is telescoped relative to the hub and the needle cannula and can be moved from a proximal position where the needle cannula is exposed to a distal position where the needle cannula is safely shielded. The latch on the fin releasably engages the shield when the shield is in the proximal position. A spring is provided between the shield and the hub to propel the shield distally relative to the hub and into surrounding relationship with the needle cannula in response to movement of the latch.
