    • The present invention relates to a carbon-containing nipple having at least one nipple thread, in particular for carbon-containing electrodes, comprising at least one inlet (also called first inlet) in the at least one nipple thread, which inlet is suitable for receiving at least one adhesive container, which is filled with a curable adhesive, in particular in all nipple threads, in particular a groove (also called first groove) which runs through the nipple thread in a transverse manner, in particular substantially perpendicular to said thread, wherein the inlet, in particular the groove, is undercut at least in sections, in particular substantially completely. The invention further relates to a nipple kit comprising at least one nipple according to the invention and at least one bag or at least one line of bags, containing a liquid or pasty thermally and/or chemically curing adhesive mixture for securing a nipple/electrode connection, wherein the bag and/or the line of bags is present in the at least one inlet. The invention further relates to a carbon-containing electrode, in particular for arc furnaces, comprising an electrode box having a box thread, and comprising an electrode kit containing the electrode and an adhesive container. The invention further relates to an electrode/nipple system, and also to the use of the nipple according to the invention and, respectively, of the electrode according to the invention or of the nipple kit or electrode kit according to the invention and, respectively, of the electrode/nipple system according to the invention when melting steel or steel scrap in an arc furnace. The invention also relates to a method for producing or extracting, recycling or processing steel, copper, silicon, calcium carbide, phosphorus or other materials in an arc furnace, and also to establishing a secure connection between the nipple and electrode. The present invention also relates to a foil bag which is filled with an adhesive mixture for securing an electrode/nipple connection. The invention finally relates to a line of foil bags, comprising at least two foil bags according to the invention.
