Abstract: A device for supporting wire bundles which pass through an opening of a structural element such as the tracks of an airplane slat. The device includes an inside spacer element which both supports and spaces apart the individual wire bundles. The spacer is supported within a hollow split bolt which is formed by two half cylinders which are held together by detachable connectors as well as by a split locking nut which is screwed onto a threaded end of the split bolt. The nut is also formed by the joining of two half nuts which are held together by detachable connectors. In this manner, the supporter can be installed around wire bundles which are already in place through the structure opening.
