The invention relates to a drug delivery device (1) comprising: - a plunger (10) disposed within a case (2), wherein the plunger (10) is slidable from a proximal position to a distal position within the case (2), - an audible indicator (12) that comprises a resilient element (12.1), wherein the resilient element (12.1) is in a first configuration when the plunger (10) is in the proximal position, the resilient element (12.1) is deflected radially outwards to a second configuration during movement of the plunger (10) from the proximal position towards the distal position, and the resilient element (12.1) moves from the second configuration towards the first configuration when the plunger (10) moves towards or reaches the distal position, thereby generating an audible and tactile signal. |
