A sheath for the needle of a hypodermic syringe to isolate the needle so as to avoid contamination and injury, particularly after use of the needle. The sheath comprises a hollow body having an opening at one end and is movable relative to the syringe needle between a first position in which the syringe needle is wholly contained within the hollow body and a second position in which the syringe needle extends through the opening in the hollow body.
