Abstract: A cable routing clip consists of a rear crosspiece, two clip arms extending from the front of the crosspiece and forming an open ended slot, a pair of retaining members extending across the open end of the slot and one or more mounting tabs extending from the rear of the crosspiece. The inside faces of the clips arms are rounded to provide edge protection to cables held by the clip and the outer faces are planar and suitable for applying indicia of the cables within the slot. A front face of a retaining member is also planar and can accept indicia. The rear mounting tabs fit into rectangular slots and include ramped faces and locking notches. When two tabs are present, one of the tabs can be shorter than the other so that a smaller rectangular slot can used on one side of a pair of mounting slots.
