1. An apparatus arranged to receive and retain a needle shield for a medicament delivery device, the apparatus comprising:
a body comprising a proximal end, a distal end, and a wall extending longitudinally between the proximal end and the distal end of the body, wherein the wall defines a void, and proximal edges of the wall define an opening in the proximal end of the body, the opening being arranged to allow at least a part of the needle shield to be received in, and at least partially fill, the void; and
two or more resiliently deformable arms adjacent each other, each of the two or more resiliently deformable arms extending from a first end connected to the wall towards the distal end of the body from a same transverse cross-sectional plane of the wall inwardly into the void, wherein each of the two or more resiliently deformable arms terminates in a second end, the second end of each of the two or more resiliently deformable arms being configured to engage the needle shield when the needle shield is received in the void and prevent the needle shield from being withdrawn from the void through the opening in the proximal end and wherein at least one of the two or more resiliently deformable arms has a first angle with respect to the wall and at least one of the two or more resiliently deformable arms has a second angle with respect to the wall that is different from the first angle when the needle shield is received in the void.
