[57] ABSTRACT
The application describes an administering device, in particular a self-injecting device, comprising a body for holding a container of a substance to be administered, a release mechanism, and means controlled by the release mechanism to discharge the said substance. The body is formed of two parts, one part being movable relative to the other, wherein one part has a trigger and the said release mechanism is partly actuated by the operation of a trigger of the said one part and partly actuated by movement of the other part relative to the said one part, but is only wholly actuated by both the operation of the trigger and the movement of the other part. Thus the discharge means cannot be accidentally actuated.
