Sub-assembly, a medicament delivery device and a method of assembling a sub-assembly

A method of assembling a sub-assembly of a medicament delivery device, comprising:

• a) providing a cap assembly comprising:
• a cap having a tubular body provided with a distal opening, the cap being configured to be mounted to a proximal end of the medicament delivery device, and
• a tubular remover received in the distal opening of the cap, the remover having a proximal end portion fixedly attached to the cap,
• wherein the remover has a plurality of radially flexible legs extending axially from a proximal end of the remover to a distal end thereof, each leg having a gripper configured to engage with a delivery member shield of the medicament delivery device, and each leg having a guide finger configured to extend distally beyond the grippers for cooperating with an internal structure of the medicament delivery device to guide radial expansion of the legs when the remover is mounted in the medicament delivery device,
• b) assembling the cap with a housing having the internal structure arranged inside the housing and provided with a proximal inclined surface, by pushing the remover into the housing,
• by pushing the remover into the housing,
• c) expanding the remover radially by means of an assembly tool inserted into the housing from a distal end thereof,
• d) pushing the guide fingers against the proximal inclined surface of the internal structure whereby the legs of the remover maintain their expanded position, and e) removing the assembly tool from the housing.
