A multi-contact connector system for electrically and mechanically connecting a lead for the delivery of electrical energy at a body site to an implantable source of the electrical energy includes a plug connector element carried at a proximal end of the lead which is received in a socket connector element carried on the source of electrical energy. The plug connector element is a radially expandable sleeve with a number of exteriorly exposed contacts respectively connected to conductors contained within the lead. Corresponding contacts are mounted in the interior of the socket connector element. The plug connector sleeve fits over a flexible expansion element contained in the socket connector element. The expansion element is operated by a toggle switch after the connector elements are engaged so as to radially expand. The sleeve of the plug connector element on which the contacts are carried is also radially expanded, so that the contacts on the connector elements are forced into tight engagement when the expansion element is actuated.
