A two part connector (10) comprises a pair of support members (15, 26) defining respective bores (14, 25) supporting respective pistons (11, 22) for movement along respective parallel axes. Pre-loaded springs (21, 32) react between the support members (15, 26) and the pistons (11, 22) to bias the pistons (11, 22) axially outwardly as far as respective stops so that their mating surfaces (12, 23) project slightly past each other. Movement of the support members (15, 26), in a direction at right angles to the two axes, causes the mating surfaces (12, 23) to wipe each other until the two axes are aligned, and a fluid connection (35, 36) admits pressurised fluid behind each piston (11, 22) to press the mating surfaces (12, 23) together when the two axes are aligned. In this manner the mating surfaces (12, 23) shear across each other, thereby wiping off any contaminants as their axes are aligned, and the pistons (11, 22) ensure that the cleaned mating surfaces (12, 23) are held tightly together to prevent either the ingress of contaminants between them, or the leakage of any fluid if the two part connector (10) is used to interconnect fluid passage ways. Alternatively the two part connector (10) may be an electrical or optical connector.
