An apparatus for removing a sheath from a syringe. The sheath provides a sterile cover for a needle of the syringe. The apparatus includes a substantially cylindrical housing defining an opening for receiving a sheath attached to a syringe, and a driver mounted on the housing and being slideable along the housing between first and second axially displaced positions. The apparatus further includes a plurality of radially deflectable fingers mounted within the housing and being coupled to the driver for movement therewith. The fingers are configured such that movement of the driver from the first to the second position causes the fingers to slide over the sheath and engage with a formation on the sheath. Movement of the driver from the second position towards the first position causes the fingers to push the sheath off the syringe. Also provided is an injection device including the apparatus.
