A syringe device (1) has an elongate plunger space (2), a receiving chamber (3) for receiving solid medicaments (4), and a hollow needle (5) arranged in the plunger space (2), and also a plunger (7) which is suitable for movement in the plunger space (2) and bears a ram (8) for pushing out the solid medicament (4). For displacement of the plunger (7) there is a plunger rod (9) which acts thereon and, for its use, can be extended telescopically out of the plunger space (2) and relative to the plunger (7) and can be coupled to the plunger by means of a lock (10). The locking of the plunger (7) to the plunger space (2) is opened or released only by complete withdrawal of the plunger rod (9) in its operative position while at the same time the plunger rod (9) is coupled to the plunger (7) in this position in the pushing direction such that the medicament can then be pushed out.
