1. A needle shield remover comprising:
a metal tubular body having a longitudinal axis, a proximal part, a distal part, and a substantially circular cross-section, where a portion of the distal part flexes radially outwards relative to the longitudinal axis when a needle shield is positioned within the tubular body, where the outward radial flexing of the portion of the distal part causes a simultaneous radial inward clamping force exerted by a portion of the proximal part on the needle shield; and
an attachment structure located at a proximal end of the proximal part of the tubular body, where the attachment structure comprises a radially outwardly directed flange that is securely held inside of a removable cap of a medicament delivery device such that the cap can rotate relative to the tubular body but is axially fixed to the tubular body.
