This invention is a lead connector seal and locking assembly for an implantable pulse generator such as a pacemaker. The pulse generator includes a header portion (24) and an enclosed metallic housing or can (22), wherein the header portion includes an orifice (26) for receiving a lead connector (30). The lead connector (30) is secured within the orifice by a defeasible active seal and a locking mechanism, which includes a sphincter seal (52) and a beveled washer (54) which is forced against the sphincter seal upon insertion of an actuator. The actuator may be a forked clip (56) inserted into a slot formed within the epoxy header in such a manner that prongs of the clip force the beveled cam to be displaced axially within the orifice of the header portion, compressing the sphincter seal to bulge radially outward and inward, thereby simultaneously contacting and sealing against the inside wall of the orifice and the body of the connector.
