Abstract: The invention relates to a system for coupling of a lightwave conductor cable with many lightwave conductors (8) on coupling elements in a housing, which contains a clamping element for the end of the lightwave conductor cable and a number of coupling elements (9), which correspond with the number of the lightwave conductors to be plugged. According to the invention the end of the lightwave conductor cable is fixable by the clamping element on a chassis part or clamping flange (2) of the housing, and the lightwave conductors, which extend out from the cable end, are surrounded with a flexible cable sleeve. The ends of the cable sleeves, which are faced toward the cable end, are connected together and anchored in the clamping element. (FIG.
