An injection device (110, figure 1) comprises a locking mechanism between a syringe carrier 127 and an end cap 111 of the injection device. It inhibits movement of the syringe carrier and syringe 114 towards an exit aperture of the injection device whilst the cap is in place. On removal of the cap, the locking mechanism is disengaged and the syringe and syringe carrier can move towards the exit aperture. This assists in preventing damage to the syringe prior to actuation of the injection device. A sleeve 121 inside the cap biases resilient beams 171 into engagement with the syringe carrier, preventing its forward motion. When the cap is removed the beams relax and no longer engage the carrier, permitting actuation of the syringe. The cap sleeve also engages needle shield 123 which is removed with the cap. |
