The present invention addresses a winged IV set (10) having a retractable needle which provides additional safety to health care workers from accidental needle sticks. The winged IV set would consist of a device body with two sets of wings, one for handling, one for retraction, a needle (16), a needle holder (14) with a nipple extension which may be connected with the catheter or IV tube, and a spring. The needle holder has opposed U-shaped arms (38) which terminate in lugs that are received in opposed openings in the device body. The pair of retracting wings (18) have a corresponding pair of tabs such that when the wings are folded, the tabs push the lugs (40) out of the openings, allowing the spring to drive the needle, and the needle holder back into the device body, where another set of openings in the body receive the lugs on the needle holder to retain the needle inside the body. After retraction the device body may be handled safely.
