A method and to an apparatus for producing a submarine cable containing a number of conductors, in particular energy conductors and/or data conductors, that are accommodated inside a cable-protecting pipe, is provided. The following method steps being carried out: a) providing the conductors and the cable-protecting sheath and conveying the same into a common assembly region; b) bringing the conductors and the cable-protecting pipe together; c) opening the separating slit in the cable-protecting pipe such that an insertion opening of the open separating slit is formed; e) holding the open separating slit open; f) inserting the conductors into the cable-protecting pipe through the insertion opening in the open separating slit; and g) releasing the open separating slit.
