A connector is described which has contacts projecting through passages of an insulator, which provides a reliable fluid-tight seal at each contact. Each insulator passage (36, FIG. 7) has first and second passage portions (51, 52) of different diameters, and each contact has contact portions (56, 57) lying in corresponding passage portions, with each contact portion having an enlargement (41, 42) lying in interference fit with a corresponding passage portion. The different diameters of the passage portions and enlargements, provide a plurality of different seal locations, with each seal location being maximally deformed only by the enlargement which lies in an interference fit therein. A front end of the connector is retained within the rear end of a second connector, by a largely U-shaped spring (100, FIG. 5) whose base (102) can be depressed to move down the opposite legs (104, 106) of the spring. The middle (110) of each leg normally lies rearward of a shoulder (130) on the first connector to prevent the first connector from being pulled rearwardly out of the second one. When the base of the spring is depressed, lower ends (116) of the spring arms are deflected (to 116A) by a cam (120) formed on the second connector housing, which presses the spring legs apart.
