A sheath for sheathing the needle of a hypodermic syringe and penetrating the rubber cap of a vial or the like, the sheath having apertures therein to allow the ingress of liquid into a zone thereof with which the needle communicates so that the liquid drawn through the needle during filling of the syringe first enters that zone before entering the needle. The sheath is further provided with a filter element and/or a needle-wiping element.
