The device comprises a syringe ( 10, 11, 12 ) and safety means comprising a protective sheath ( 16 ) capable of adopting, relative to the syringe body, both an injection configuration in which the syringe needle ( 11 ) projects beyond said sheath, and a protection configuration in which the needle extends inside the sheath. The device includes a trigger member ( 30 ) enabling it to pass from the injection configuration to the protection configuration at the end of the injection stroke. It comprises means ( 34 ) for defining a first end-of-injection-stroke situation in which the trigger member ( 30 ) is unsuitable for causing the device to pass from the injection configuration to the protection configuration, and a second end-of-injection-stroke situation in which such passage is possible.
