Cable connecting device

A cable connecting device comprising an electrically conductive housing surrounding a first Adernfixierteil for fixing the wires of a first data cable and a second Adernfixierteil for fixing the wires of a second data cable and an electrical connection means for electrically connecting each one wire of the first data cable having a wire of the second data cable and that with the shields of the two data cable is electrically connectable. Thus, the cores and screens of the two data cables can be connected within a short time cost without special tools to each other, the connecting means comprises a plurality held in the housing, electrically conductive connection elements, each having a first contact portion for contacting a strand of the first data cable and a second contact portion for contacting have one wire of the second data cable. The wire fixing parts each have a plurality of contact areas to which an end portion of a wire can be applied. The wire fixing parts are insertable into the housing, wherein the first contact portions each engage in an abutment region of the first Adernfixierteils and the second contact areas of the connecting elements in each case in a contact area of ​​the second Adernfixierteils.
