description An injection device (110) is described having a housing (112) that receives a syringe (114) having a sealed boot (123) that covers its needle (118). A releasable locking mechanism retains the syringe (114) in its retracted position. A sleeve (119) projects from the exit aperture (128) and can be depressed to release the locking mechanism. A removable threaded cap (111) closes the housing (112), covers the exit aperture (128) and the sleeve (119), thus preventing the locking mechanism from being released, and engages the boot (123) on the syringe (114). When the cap (111) is removed, it takes the boot (123) with it, no longer closes the exit aperture (128) and no longer prevents the locking mechanism from being released. Then, the locking mechanism can be released and the injection cycle begun. Dispositif d~injection (110) comportant un corps (112) recevant une seringue (114) dotée d~une tétine étanche (123) recouvrant son aiguille (118). Un mécanisme de verrouillage déclenchable maintient la seringue (114) dans sa position rentrée. Une douille (119) faisant saillie de l~ouverture de sortie (128) peut être enfoncée pour déclencher le mécanisme de verrouillage. Un embout fileté amovible (111) bouche le corps (112), recouvre l~ouverture de sortie (128) et la douille (119), en empêchant ainsi le déclenchement du mécanisme de verrouillage, et emboîte la tétine (123) sur la seringue (114). Lorsque l~embout (111) est retiré, il emmène avec lui la tétine (123), cesse de recouvrir l~ouverture de sortie (128) et ne bloque plus le déclenchement du mécanisme de verrouillage. Celui-ci peut donc être déclenché pour réaliser un cycle d~injection.
