Abstract
A veterinary syringe comprises a base body for receiving a syringe barrel with a guiding element for a plunger rod that is guided therein so as to be movable in a longitudinal direction. At one end of the plunger rod, a plunger is attached that extends into the syringe barrel. The syringe further comprises a handle and an operating lever. The operating lever is connected to a guiding element that engages with a toothed rack associated with the plunger rod, and with a locking device for the plunger rod that engages with the toothed rack. The locking device acts as a locking slider disposed inside the guiding element and has an opening through which the plunger rod is guided and extends into the toothed rack from below, locking the toothed rack so as to prevent it from withdrawing.
