A threading device that provides a multi-strand thread integrally connected to a wire cable needle at one or both ends thereof. The thread is formed of at least one thread filament that is folded onto itself to form a bundle of strands with filament bends at the end of the thread. At least one wire filament is also provided that is folded onto itself to form wire filament bends that are interlocked with the corresponding thread filament bends. The joined bends of the thread filament and wire filament form a tapering interlocking interconnection that extends integrally between the thread and the needle. The thread and wire strands are twisted in opposite directions about a longitudinal axis to bind the wires and strands to form an elongated integral threading device with a tapering wire cable needle at one or both ends thereof. The needle tapers from a reduced end to the cross-sectional dimension of the thread. The interlocking interconnection tapers due to selective layout of the successive interconnected thread filament bends and wire filament bends. The bends are spaced apart longitudinally along the axis of the device before it is twisted. Therefore, the total cross-sectional dimension of the combined strands is not produced abruptly in the finished twisted product but is introduced gradually along the length of the interlocking interconnection.
