<p num="1"><br/><br/><br/>The invention relates to a syringe for administering multiple doses of a <br/>medicinal substance contained therein, consisting of: a cylindrical tube (1) <br/>comprising an injection opening (3) and a mouth (2) and a longitudinally-<br/>mobile drive plunger (4), and an actuation rod (5) for connecting to the <br/>plunger, said rod (5) being equipped with detachable dose-limiting means (6) <br/>which project out from the rod such as to exceed the inside diameter of the <br/>tube in order to prevent the forward movement of the rod and the plunger <br/>inside the tube. In addition, mouth-limiting means (7, 70) co-operate with <br/>locking means (8, 60) such as to prevent the reverse movement of the rod. When <br/>closed, the injection opening (3) is provided with an elastomer seal (9) which <br/>can be perforated with a sharp element. Moreover, one end of a hypodermic <br/>needle device (10) is coupled to the injection opening and said needle device <br/>can perforate the end elastomer seal and communicate with the interior of the <br/>tube and be equipped with an injection needle at the opposing end thereof.<br/>
