The present invention relates to a medicament delivery device (10) comprising: a housing (12, 14) having a distal and an proximal end, said housing being adapted to receive a medicament container (20) with a delivery member (23) or with a connectable delivery member for delivery of a medicament a drive mechanism (40) arranged to act on the medicament container (20) for providing automatic delivery of the medicament an actuator (42) interactively connected to the drive mechanism (40) for holding the drive mechanism in a pre-tensioned state a biased delivery member cover (26) positioned at least partially and axially movable within the housing (12, 14), said biased delivery member cover (26) being interactively connected to the actuator (42), such that when said biased delivery member cover (26) is pressed against a delivery site said actuator (42) releases the drive mechanism (40) from the pre-tensioned state and a signal delay mechanism (84) operably connected to said drive mechanism (40) for generating an audible and/or tactile and/or visual signal indicating that the medicament has been completely delivered. The invention is characterized in that the signal delay mechanism (84) comprises an activator (74) interactively arranged to said drive mechanism, a signal generating element (86) interactively connected to the activator (74) and to an actuator (42) of the drive mechanism, and a delay element (100) operably connected to the housing and to the signal generating element (86) for delaying said generation of an audible and/or tactile and/or visual signal.
