11, ABSTRACT:, A metal connector for the end of an internally and externally plastics coated metal tube maintains the metal of the tube for example aluminium, out of contact with the metal of the connector, for example brass, and thereby avoids problems of anodic corrosion. This is achieved by forming the male portion of the connector with a tapered shant over which the tube end is to be forced, and a shoulder to act as a stop for the tube end, the shoulder being of such relatively shallow depth that it abuts the internal plastics coating but not the metal of the tube.
