An injection aid for use with an injection device, such as a safety syringe, for example, is disclosed. The injection aid employs a flexible clip-based design to compensate for manufacturing tolerances associated with the injection device. The injection aid includes a body and a lever mounted to the body, the lever being configured to rotate about the body. The injection aid may further include gears rotate with rotation of the lever, and which function to remove a needle shield from the injection device. The body positions the injection device so as to ensure consistent injection depth.
