A "single use! syringe including, a barrel defining a bore which in use receives liquid to be dispensed, a plunger movable within the bore away from a proximal end towards a distal end to dispense the liquid a needle mount for interacting with a needle which is located adjacent the distal end of the barrel when liquid is dispensed from the barrel, the needle mount configured to interact with the plunger so as to move therewith towards the proximal end. A latching means associated with the needle mount that in an active condition restrains the needle mount from moving towards the proximal end of the barrel, the latching means having a detent that when the latching means is in an active condition engages the barrel adjacent the periphery of the bore, and when the latching means is in an inactive condition the detent is located within the bore to allow the needle mount to retract within the bore away from the distal end towards the proximal end.
