An injection device comprising a housing in which can be mounted a syringe comprising



a barrel for holding a volume of medicament,
a needle at one end of the barrel and
a plunger axially-moveable in the barrel to a forwardmost position,

the injection device further comprising a syringe support means for supporting the barrel at an axial location at or forward of the forwardmost position of the plunger and having a reaction surface for the syringe, whereby in use said reaction surface provides an axial compressive force on said barrel when a forward axial force is applied to the plunger.
