Adapters for use with an angiographic injector. A face plate adapter includes a channel for receiving a rearward end of a syringe. First and second mounting flanges on the adapter overlay a portion of the channel, to cooperate with mounting flanges on a rearward end of the syringe, so that the syringe mounting flanges may be inserted between the adapter mounting flanges, and then rotated in the channel behind the adapter mounting flanges, to thereby lock the syringe to the adapter. The adapter further includes one or more locking pins, which in a locked position extend across the channel, to block the syringe from rotating in the channel and thereby prevent a syringe from being dismounted from the adapter. A collar incorporated in the adapter interacts with a drive ram of the injector to move the locking pins into their locked position whenever the ram is forward of a rearwardmost position. A ram tip adapter includes a movable member having a connector for engaging a connector on a rearward face of a plunger, and a cam surface for interacting with the face plate adapter. The interaction between the cam surface and the face plate adapter causes the connector of the movable member to move to an engaging position in which the connector engages with the connecting structure of the syringe, only when the ram is forward of its rearwardmost position.
