An injection device comprises a housing 112 having a syringe 114 with a discharge nozzle 118. The syringe 114 is movable between a retracted position in which the discharge nozzle 118 is contained within the housing 112 and an extended position in which the discharge nozzle 118 extends from the housing 112. There is a syringe cap for enclosing the discharge nozzle 118. The syringe cap is removable from the syringe 114 by rotation relative to the syringe 114. A syringe carrier 151 in the housing is adapted to restrain rotation of the syringe 114 relative to the housing 112 as the cap is removed. |
