A cardiac pacemaker including implantable housing means (8), electrical signal generating means enclosed within said housing, an electrode conductor (6) for conveying pacing signals to the heart, and apparatus for maintaining sealable electrical interconnection between said generating means and said electrode. Said apparatus comprises a pair of terminal means (2,4) which cooperate through engageable camming surfaces (16,32) to clamp the lead between lead clamping jaws on a collet (20). The pacemaker housing may be bifurcated, with one portion containing the interconnection apparatus, and the other containing the pacemaker electronics and batteries. The two portions are assembled separately and subsequently combined structurally and electrically. One of the terminal means (4) is provided with appropriate slots (40) to engage protuberances from a spanner, thereby facilitating quick and accurate insertion or removal of the electrode conductor.
