Abstract
Cable plug and method of manufacture in which hardened plugging compound surrounds individually insulated conductors and a radially resilient spring is placed around the compound which holds the spring permanently in a resiliently expanded condition to compress the compound onto the individual insulations of the conductors. In one arrangement a sleeve surrounds and intimately contacts the compound and at least one rib on the inner surface of the sleeve is urged against a complementary groove in the compound by the spring.
