Abstract: A multipurpose boot for use with a jacketed round-to-flat multiconductor electrical cable comprises in one embodiment a sheet of adhesive coated non-conductive flexible plastic material appropriately cut and scored to define a center panel, a pair of fold-over flaps and a tab. In use, the boot is placed about the cable with the tab end disposed at the end of the cable and the end opposite the tab end secured to the cable jacket. When the end of the cable is inserted into a connector for mass termination the tab is inserted along with it. When the connector is subsequently crimped closed the boot effectively connects the connector to the cable jacket so as to physically protect the cable in the area where it is neither flat nor round and to provide strain relief. In another embodiment of the invention the boot is attached at one end to the cable jacket and at the other end to a strip of carrier tape located at the end of the cable for holding the conductors in side by side alignment at that location.
