Abstract

A drug delivery device including a case adapted to hold a medicament container, a plunger disposed within the case and slidable from a proximal position into a distal position for delivering a medicament from the medicament container, and an audible indicator that is arranged within a case pocket lateral to the plunger and that is in operative connection with the plunger. The audible indicator includes at least one indicator spring and at least one locking element, where the indicator spring is biased by the locking element, and the indicator spring relaxes due to a release of the locking element by a movement of the plunger.
