Medicament Delivery Device and Method of Assembling the Same

A device for injecting a medicament, comprising:

• a housing having a distal end opening and a proximal end opening;
• a needle guard extending from the proximal end opening;
• an activation member extending from the distal end opening and movable relative to the housing from an initial position to a final position;
• and
• a final position lock disposed on an inner surface of the housing and configured to restrict movement of the activation member relative to the housing when the activation member is in the final position.

A method of assembling a device for injecting a medicament, the method comprising:

• arranging a needle guard in a housing of the device, wherein the housing has a distal end opening and a proximal end opening, wherein the needle guard is arranged such that the needle guard extends from the proximal end opening;
• and
• arranging, via the distal end opening of the housing, an activation member in the housing such that the activation member extends from the distal end opening and is movable relative to the housing from an initial position to a final position,
• wherein a final position lock is disposed on an inner surface of the housing and configured to restrict movement of the activation member relative to the housing when the activation member is in the final position.
