The invention relates to a disposable syringe encompassing an ampoule member that forms a chamber and is used for holding the fluid to be injected, a sealingly guided ampoule plunger which can be axially moved within the chamber, and a male taper of a Luer taper at the distal end of the ampoule member, and an adapter encompassing a female taper of a Luer taper at the proximal end of the adapter and an outlet for the fluid to be injected without a needle at the distal end of the adapter, and an autoinjector encompassing a receiving device for the coupled and fluid-filled combination of the disposable syringe and the adapter, said receiving device being designed to maintain the positive connection between the disposable syringe and the adapter and support the ampoule member of the disposable syringe. The autoinjector further encompasses a distal skin coupling element which forms a skin contact surface for the needle-free injection through or into the skin, is curved, and has a central nozzle cover that is shaped to be complementary with the outlet of the adapter and receives the outlet of the adapter in a flush manner in the area of the skin contact surface during the needle-free injection by means of the nozzle cover. The autoinjector finally encompasses an injection device which is designed to axially move the ampoule plunger according to a predefined pressure profile.
