A device for transferring liquid between the body of a patient and a syringe includes a syringe barrel defining a bore, a plunger that may slide through the bore to force liquid into or out of the bore, and a pump capable of sliding the plunger. The pump housing positively connects to the bore by sliding a protrusion formed on the exterior of the pump housing into an indentation formed within the interior surface of the bore.
