- a substantially cylindrical housing defining an opening for receiving a sheath attached to a syringe;
a driver mounted on the housing and being slideable along the housing between first and second axially displaced positions; and
a plurality of radially deflectable fingers mounted within said housing and being coupled to said driver for movement therewith, the fingers being configured such that movement of said driver from said first to said second position causes said fingers to slide over said sheath and engage with a formation on said sheath, and movement of the driver from said second position towards said first position causes said fingers to push the sheath off the syringe,wherein the driver is in the form of a sleeve, said sleeve arranged coaxially about the housing and in slidable engagement therewith, andwherein the sleeve remains mounted on the housing in both said first and second 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.
