A syringe is proposed having a syringe cylinder (3), a closure plug (7) which can move in the syringe cylinder (3), and having a plunger rod (13) which interacts with said closure plug (7). Said syringe is distinguished by a safety device (19) which prevents the closure plug (7) from sliding back in the syringe cylinder (3) in every position which said closure plug (7) assumes in the syringe cylinder (3), and by a locking element (21) which acts on the plunger rod (13) in every position which said plunger rod (13) assumes in the syringe cylinder (3).
