An improved syringe is provided for use in a medication infusion pump for operating the syringe to administer a selected medication to a patient. The syringe comprises a hollow barrel adapted to receive a supply of the selected medication for delivery through infusion tubing or the like to the patient, in combination with a syringe plunger formed with an open-sided threaded half nut for engaging a motor-driven lead screw of the medication infusion pump when the syringe is correctly seated within a syringe compartment formed within a pump housing. The half nut on the syringe plunger includes detent tabs for snap-fit engagement with the pump lead screw to provide a direct drive connection therebetween. A compartment door on the pump housing can be moved to a closed position, following syringe placement into the syringe compartment, only when the plunger half nut is properly engaged with the lead screw.
