A safety needle assembly having a rigid housing that encloses a locking mechanism, an actuator that is operable to slide a sheath over the tip of the needle to prevent accidental sticks after the needle has been used, and an actuator that is operable in response to the final end movement of the syringe plunger to effect movement of the actuator over the needle tip. The housing is made in a standard size that is mountable on a connection port formed on a syringe barrel that can have a much greater diameter than the connection port. An adapter is provided for mounting a standard needle having a Luer lock to enable a health care professional the flexibility to use conventional needles to load medicine into the syringe barrel then replacing with a safety needle assembly for injection of the medicine.
