2. The split, non-metallic electrical insulating bushing according to claim 1 , wherein the aperture of the second insulating bushing portion is threaded and wherein the fastener has threads for engagement therewith.
3. The split, non-metallic electrical insulating bushing according to claim 1 , wherein the aperture of the second insulating bushing portion passes through the second end of the second insulating bushing portion and wherein the fastener is dimensioned to pass through said aperture.
4. The split, non-metallic electrical insulating bushing according to claim 3 , wherein the fastener is secured to the second end of the second insulating bushing portion by a nut.
5. The split, non-metallic electrical insulating bushing according to claim 1 , wherein the first bushing portion has a flange attached to the rim, the flange projecting radially inward so as to overlie the terminating end of an electrical conduit when installed thereon and wherein the second bushing portion has a flange attached to the rim, the flange of the second insulating bushing projecting radially inward so as to overlie the terminating end of an electrical conduit when installed thereon.
6. The split, non-metallic electrical insulating bushing according to claim 1 , wherein the rim of the first insulating bushing portion and the rim of the second insulating bushing portion each include threads formed on an interior surface thereof, said threads dimensioned for threading engagement with threads formed on a terminating end of an electrical conduit.
7. The split, non-metallic electrical insulating bushing according to claim 1 , wherein the means for allowing the first end of the first insulating bushing portion and the first end of the second insulating bushing portion to rotate with respect to each other includes a hinge pin and where the first end of the first insulating bushing portion and the first end of the second insulating bushing portion have bores formed therein for receipt of said hinge pin.
8. The split, non-metallic electrical insulating bushing according to claim 7 , wherein the hinge pin is fabricated from zinc plated steel.
9. The split, non-metallic electrical insulating bushing according to claim 1 , wherein the rim of the first insulating bushing portion and the rim of the second insulating bushing portion end each include a plurality of ribs dimensioned to assist gripping the bushing.
10. The split, non-metallic electrical insulating bushing according to claim 1 , wherein the first insulating bushing portion and the second insulating bushing portion are formed from a thermoplastic material.
11. The split, non-metallic electrical insulating bushing according to claim 1 , wherein the fastener is a machine screw.
12. The split, non-metallic electrical insulating bushing according to claim 1 , wherein the fastener is a self-tapping machine screw.
13. The split, non-metallic electrical insulating bushing according to claim 1 , wherein a retaining washer is positioned on the fastener after passage of the fastener through the bore on the second end of the first insulating bushing portion.
14. The split, non-metallic electrical insulating bushing according to claim 13 , wherein the first end of the second insulating bushing portion include a recess formed around the aperture, said recess dimensioned for receipt of the retaining washer when the bushing is in the closed configuration.
15. The split, non-metallic electrical insulating bushing according to claim 1 , wherein the second end of the first insulating portion further comprises a projecting pin and wherein the second end of the second insulating portion further has an orifice formed therein dimensioned for receipt of the projecting pin when the split, non-metallic insulating bushing is in its second closed configuration, thereby providing enhanced securement of the split non-metallic insulating bushing when in the second closed configuration.
16. The split, non-metallic electrical insulating bushing according to claim 15 , wherein the aperture of the second insulating bushing portion is threaded and wherein the fastener has threads for engagement therewith.
17. The split, non-metallic electrical insulating bushing according to claim 15 , wherein the first bushing portion has a flange attached to the rim, the flange projecting radially inward so as to overlie the terminating end of an electrical conduit when installed thereon and wherein the second bushing portion has a flange attached to the rim, the flange projecting radially inward so as to overlie the terminating end of an electrical conduit when installed thereon.
