Abstract
An injection device includes an injection complete indicator which includes its own bias and which is latched into a retracted position as the injection device is cocked. Upon firing the injection device, the injection complete indicator is kept in its retracted position until towards the end of the forward stroke of the drive mechanism, whereupon the injection complete indicator is unlatched and shoots forwardly under the influence of the bias to impact an abutment to generate an audible/tactile indication along with a visual indication.
