The invention relates to a resealable port (2), or an injection site (24), for use with a syringe cone (16), the port being formed with a housing including a conduit (1) sealed by a resealable diaphragm (7) wherein a sealing annulus (6) is juxtaposed to, and interacts with, the diaphragm (7) to form an annulus and diaphragm assembly whereby the arrangement of the housing and the assembly is such that action of the syringe cone (16) as it passes through the diaphragm generates a cantilever action about a point (12) which serves to seal the diaphragm and the annulus in the housing.
