An improved seal for a high voltage igniter cable connector for aircraft applications. An insulator projecting from the cable connector extends into a tubular insulator in the igniter. An electrical contact at the free end of the connector insulator is urged into contact with a terminal in the igniter. A resilient annular seal is located between an annular shoulder or step on the connector insulator, the interior and end surfaces on the igniter insulator, the igniter shell and a spring cap or retainer. The spring retainer is shaped to force the resilient seal both against the connector insulator shoulder or step and against the end of the igniter insulator. Above the insulator shoulder or step, the compressed seal expands to form a radial seal between the igniter and connector insulators. Above the igniter insulator end, the compressed seal expands to form a seal between the igniter insulator end and the connector insulator and, preferably, also to the igniter shell.
