connecting element 14 this will be discussed in more detail below in particular in conjunction with fig5 a and 5b proceeding from the first data cable 4 the individual core pairs 4 a 4 b are severed specifically for this purpose a respective pair shield 8 is severed in the middle in such a way that two partial shields 36 are realized per core pair 4 4 a these are in each case approximately u shaped as viewed in cross section the partial shields 36 or the respective cores 7 with their partial shield 36 are then preferably twisted through 90 u00b0 in such a way that an open region 38 of the respective partial shield 36 is oriented outward therefore in the direction of a respective adjacent core 7 there is at least one part of one or more partial shields 36 the individual cores 7 are thus reciprocally shielded with respect to one another in this case too the connecting element 14 expediently has a housing 26 which forms a shielding to the outside the open regions 38 are oriented toward the housing 26 in such a way that the open region 38 is thus shielded by the housing 26 the cores 7 which are prepared in this way and which have the partial shields 36 are transitioned or converted within the connecting element 14 from the core distribution illustrated in fig5 a to the core distribution illustrated in fig5 b in a further structural variant the connecting lines 16 are formed.
