Abstract: A metallic connector (1) comprises a female housing (2) in which a retaining ring (6) is made of a material which is harder than the female housing (2) so that the retaining ring (6) is urged into the inner wall of the female housing during a pressing operation. An annular sealing member (7) provides a water tight seal. In the connection assembly, the retaining ring (6) deforms an end of a metallic item (4) provided within the female housing to connect the female housing to the metallic item. The connection assembly is formed by a pressing operation which causes—the retaining ring (6) to deform both the female housing (2) and the metallic item (4) to be connected.
