An electric cable connection for a single or multi-core power and control cable, in which the electrically insulating and sealing coating consists of a cast resin or shrink sleeve (12, 9) and in which the cores (8) in the region of the connector (5) are surrounded by a dimensionally stable coating (2), covered in turn by an outer sleeve covering the core insulation (1) and in which, besides the electrically insulating and damp-proofing protection, there is over each electric core connection, and electrically insulating, damp-repellent, high-temperature and thus fire-resistant moulding (2) remaining dimensionally stable under the action of heat as a casing for each individual core connection (8, 5) permanently spaced apart by heat-resistant spacers, where the dimensionally stable moulding (2) advantageously consists of a fireproof ceramic or a high-temperature-resistant quartz glass or quartz substance.
