A hand-held power injector (60) is provided for injecting liquid, such as contrast media, into the vascular system of a mammal. The device comprises a pistol-shaped housing which encloses a battery-powered D.C. motor for constant-rate delivery of liquid from a syringe (80). The hand-held power injector includes an engagement feature connecting the syringe (80) and the power injector which prevents inadvertent activation of the power injector. The engagement feature comprises a flange (92) on the syringe arranged to engage in a slot (72) of the casing and to operate a syringe sensing switch (124), thereby permitting power assisted injection to be commenced by a user.
