Abstract of the Disclosure A locking device attached to the exterior of a syringe barrel includes a flat body having a circular opening therein for passage of a syringe plunger reciproc- atably therethrough. Arms depend from the flat body to frictionally hold the device against rotation with respect to the syringe barrel when a syringe plunger is rotated to engage the locking device. At least two ridges extend chordally across the circu- lar opening, the distance between the ridges being selected so that the ridges engage the syringe plunger when the plunger is oriented in one position but not when the plunger is oriented in another position.
