An auto-injector demonstration device for simulating the delivery of medication has an elongated body encompassing a needle guard member with locking slots circumscribing a transparent window member having stop elements. A plunger, electronically controlled by a transmission motor, has bump-out elements. In use, the needle guard member is pressed against the injection site to actuate the transmission motor. This moves the plunger through the window member to simulate the medication delivery. When the plunger reaches its terminal position, the bump-out elements compel the stop elements on the window member outward. When the user allows the needle guard member to ease back into the original extended position, the stop elements will engage with the locking slots through the needle guard member to lock and prevent the needle guard from retracting into the window member.
