Describe is an auto-injector (1) comprising a syringe carrier (7) arranged to retain a syringe (3), a plunger (9) arranged to displace a stopper (6) within the syringe (3), a feedback component (28) retainable in a first position and biased towards a second position, a pin (28.4) disposed on the feedback component (28), and an exterior component (12, 13) having a bore (13.7). The feedback component (28) moves from the first position to the second position when the plunger (9) during displacement of the stopper (4) reaches a predetermined position. The pin (28.4) enters the bore (13.7) when the feedback component (28) is in the second position. |
