A handling device for use with a medical injector ( 11 ) including a protective sheath ( 17 ) for a needle ( 14 ) has a carrier ( 20 ) with an outer cylindrical wall ( 21 ) and a coaxial inner tube ( 33 ) which is a close sliding fit over the protective sheath ( 17 ). A cylindrical sleeve ( 24 ) is slidably mounted within the outer cylindrical wall ( 21 ) and is adapted to receive the cylindrical body ( 12 ) of the injector ( 11 ). A bushing ( 25 ) is slidably retained within the cylindrical sleeve ( 24 ) and is configured to receive a boss ( 13, 15 ) supporting a needle ( 14 ) at the forward end of the injector body, a spring ( 29 ) urging the bushing ( 25 ) towards the rear of the sleeve. A plug ( 35 ) is mounted on the carrier ( 20 ) and is engaged by the forward end of the protective sheath ( 17 ) when an injector is received within the cylindrical sleeve, so that the plug is projected forwardly from the carrier when the injector is fully engaged. On removing the carrier ( 20 ) from the injector ( 11 ), the plug ( 35 ) remains projecting therefrom and the sheath ( 17 ) is removed together with the carrier.
