An implantable electronic unit (1, 30, 50), in particular a cardiac pacemaker, having at least one substantially socket-shaped connecting arrangement (3, 32, 33, 52, 53) arranged in the header (2, 31, 51) for a plug disposed at the proximal end of an electrode line (4, 34, 35, 54, 55), a plug receiving means (7, 60, 61) having a contact element (8, 20, 37, 38, 58, 59) for the deferent pole (6, 39, 40, 56, 57) of the plug, wherein the connecting arrangement includes a locking device (15) which secures the fit of the plug in relation to a tensile force acting in the axial direction and which can be operated by a hand lever (11) on the outside of the header. The locking device (15) includes the contact element (8, 20, 37, 38, 58, 59) and a locking cam (9, 36, 62, 63) mounted eccentrically in the connecting arrangement (3, 32, 33, 52, 53), wherein the resiliently arranged contact element embraces the deferent pole (6, 39, 40, 56, 57) of the plug in positively locking relationship and is in operative engagement with the locking cam (9, 36, 62, 63) in such a way that upon a rotary movement of the locking cam (9, 36, 62, 63) a variation in the position and/or the form of the contact element relative to the deferent pole (6, 39, 40, 56, 57) of the plug is forced for the purposes of making a force-locking connection between the deferent pole and the contact element.
