A medicament delivery device comprising a housing, a plunger rod and a signal delaying assembly, the signal delaying assembly comprising: - a delay female member containing a fluid, - a delay male member having at least one passage, - a delay unit connected to the delay female member or to the delay male member, wherein a relative movement between the male member and the female member and towards each other causes a transfer of said fluid from said female member through the at least one passage for slowing said movement, characterized in that the delay unit is releasably connected to a signal generating assembly for delaying at least one feedback signal, and wherein the signal delaying assembly further comprises a support element releasably connected to the delay unit such that the relative movement between the delay female member and the delay male member causes a relative movement between the delay unit and the support element causing the signal generating assembly to be released from the delay unit for generating the at least one feedback signal, and wherein the delay unit is movably arranged in relation to the support element from a delaying position in which the delay unit is in contact with the support element and with the signal generating assembly, to a released position in which the delay unit is disconnected from both the support element and the signal generating assembly, and wherein the signal generating assembly comprises a signal generating member and a force element and wherein the force element is arranged tensioned between said signal generating member and the plunger rod for moving the plunger rod and the signal generating member, and wherein the signal generating member is releasably connected to a holding unit of the medicament delivery device, and wherein a pre-determined proximal and longitudinal movement of the plunger rod in relation to the holding unit allows the signal generating member to be released such that the force element forces the signal generating member to move distally in relation to the holding unit, and wherein the delay unit is in contact with the signal generating member such that the movement of the signal generating member causes the delay unit to move from the delaying position to the released position such that the signal generating member can move distally in relation to the delay unit. - a delay female member containing a fluid, - a delay male member having at least one passage, - a delay unit connected to the delay female member or to the delay male member, wherein a relative movement between the male member and the female member and towards each other causes a transfer of said fluid from said female member through the at least one passage for slowing said movement, characterized in that the delay unit is releasably connected to a signal generating assembly for delaying at least one feedback signal, and wherein the signal delaying assembly further comprises a support element releasably connected to the delay unit such that the relative movement between the delay female member and the delay male member causes a relative movement between the delay unit and the support element causing the signal generating assembly to be released from the delay unit for generating the at least one feedback signal, and wherein the delay unit is movably arranged in relation to the support element from a delaying position in which the delay unit is in contact with the support element and with the signal generating assembly, to a released position in which the delay unit is disconnected from both the support element and the signal generating assembly, and wherein the signal generating assembly comprises a signal generating member and a force element and wherein the force element is arranged tensioned between said signal generating member and the plunger rod for moving the plunger rod and the signal generating member, and wherein the signal generating member is releasably connected to a holding unit of the medicament delivery device, and wherein a pre-determined proximal and longitudinal movement of the plunger rod in relation to the holding unit allows the signal generating member to be released such that the force element forces the signal generating member to move distally in relation to the holding unit, and wherein the delay unit is in contact with the signal generating member such that the movement of the signal generating member causes the delay unit to move from the delaying position to the released position such that the signal generating member can move distally in relation to the delay unit.
