The invention concerns a cable lead-in, in particular one for the control unit of a vehicle internal-combustion engine. The lead-in duct has an elastic sealing element which is penetrated by at least one cable duct and which seals by acting in conjunction with a pressing device. The invention proposes that the sealing element (15) has at least one cable-holding slit (24) which opens out in the cable duct (25) and can be held tightly closed by the pressing device.
