1. A slip conduit connector for use in installing electrical conduit between two fixed locations, comprising: a hollow cylindrical member having a first end and a second end, at least one threaded bore positioned near the first end passing through the cylindrical member, each bore for receipt of a fastener; anda flange circumferentially extending around the cylindrical member inward from the second end, and an outer threaded region extending from the second end of the cylindrical member toward said flange, the threaded region dimensioned to receive a locknut;wherein a closed-ended slot is formed through the cylindrical member between the flange and the at least one threaded bore closest to the second end, the slot dimensioned to allow viewing inside the cylindrical member to ensure entry of an electrical conduit past all of the at least one threaded bore, thereby ensuring mechanical and electrical securement of said electrical conduit to said hollow cylindrical member when said fastener is secured in the at least one bore. 2. The slip conduit connector according to claim 1, further comprising indicia positioned on the hollow cylindrical member, the indicia containing instructions regarding use of the slip conduit connector. 3. The slip conduit connector according to claim 2, wherein the at least one threaded bore is two threaded bores adjacent one another. 4. The slip conduit connector according to claim 3, wherein the two threaded bores are positioned along a longitudinal path of the hollow cylindrical member, and wherein the closed-ended slot is positioned so as to be in linear alignment with the two threaded bores. 5. The slip conduit connector according to claim 4, wherein the flange is integrally formed on the cylindrical member. 6. The slip conduit connector according to claim 5, wherein the hollow cylindrical member includes an internal stop in the vicinity of the flange, the stop dimensioned to contact an end of an electrical conduit sized for entry into the slip conduit connector. 7. The slip conduit connector according to claim 6, wherein the threaded region of the cylindrical member has an inner diameter less than an inner diameter of a remainder of the hollow cylindrical member, thereby forming said stop at one end of the threaded region in proximity to said flange. 8. The slip conduit connector according to claim 1, wherein the at least one threaded bore is two threaded bores adjacent one another. 9. The slip conduit connector according to claim 1, wherein the two threaded bores are positioned along a longitudinal path of the hollow cylindrical member, and wherein the slot is positioned so as to be in linear alignment with the two threaded bores. 10. The slip conduit connector according to claim 1, wherein the flange is integrally formed on the cylindrical member. 11. The slip conduit connector according to claim 1, wherein the hollow cylindrical member includes an internal stop in the vicinity of the flange, the stop dimensioned to contact an end of an electrical conduit sized for entry into the slip conduit connector. 12. The slip conduit connector according to claim 11, wherein the threaded region of the cylindrical member has an inner diameter less than an inner diameter of a remainder of the hollow cylindrical member, thereby forming said stop at one end of the threaded region in proximity to said flange. 13. The slip conduit connector according to claim 1, wherein the hollow cylindrical member is fabricated from zinc plated steel. 14. The slip conduit connector according to claim 1, wherein the hollow cylindrical member is fabricated from zinc alloy. 15. The slip conduit connector according to claim 1, wherein the hollow cylindrical member includes a plurality of longitudinal ribs extending along a surface of the hollow cylindrical member. 16. The slip conduit connector according to claim 15, further comprising a second flange positioned on the first end of the hollow cylindrical member. 17. An electrical conduit system to span a first electrical panel box and a second electrical panel box separated from each other comprising: an electrical conduit;a conduit connector having a hollow cylindrical member dimensioned to receive said electrical conduit, the cylindrical member with an outer threaded region positioned at a first end, the threaded region dimensioned to receive a locknut so as to secure the conduit connector to the first panel box by passage of said threaded region through an opening in said first panel box and tightening said locknut on the threaded region, the conduit connector having at least one threaded bore passing through the conduit connector for receipt of a fastener to secure said electrical conduit positioned inside the hollow cylindrical member; anda slip conduit connector having a hollow cylindrical member dimensioned to receive said electrical conduit, the hollow cylindrical member having a first end and a second end, at least one threaded bore positioned near the first end of the cylindrical member for receipt of a fastener, a flange circumferentially extending around the cylindrical member inward from the second end, and an outer threaded region extending from the second end of the cylindrical member toward said flange, the threaded region dimensioned to receive a locknut so as to secure the slip conduit connector to the second panel box by passage of said threaded region through an opening in said second panel box and tightening said locknut on the threaded region, the cylindrical member having a closed-ended slot formed therein between the flange and the at least one threaded bore closest to the second end, the slot dimensioned to allow viewing inside the cylindrical member to ensure entry of the electrical conduit past all of the at least one threaded bore, thereby ensuring mechanical and electrical securement of said electrical conduit to said slip conduit connector when said fastener is secured to the at least one bore. 18. The electrical conduit system according to claim 17, wherein the hollow cylindrical member of the slip conduit connector further comprises indicia positioned on the hollow cylindrical member, the indicia containing instructions regarding use of the slip conduit connector. 19. The electrical conduit system according to claim 17, wherein the hollow cylindrical member of the slip conduit connector includes an internal stop in the vicinity of the flange, the stop dimensioned to contact an end of an electrical conduit sized for entry into the slip conduit connector. 20. A method of installing electrical conduit so as to span a first electrical panel box and a second electrical panel box separated from each other, comprising: attaching a conduit, connector having a first end and an outer threaded region at said first end, through an opening in said first panel box and tightening a threaded locknut to the threaded region of the conduit connector so as to secure the conduit connector to the first panel box;inserting a first end of the electrical conduit into a slip conduit connector, the slip conduit connector having a hollow cylindrical member dimensioned to receive said electrical conduit,attaching the slip conduit connector having an outer threaded region through an opening in the second panel box and tightening a threaded locknut to the threaded region of the slip conduit connector so as to secure the slip conduit connector to the second panel box;inserting a second end of the electrical conduit into a second end of the conduit connector so as to contact an internal stop of the conduit connector, determining if the electrical conduit is visible in a closed-ended slot formed through the cylindrical member of the slip conduit connector, and if visible in said closed-ended slot,securing the electrical conduit to the conduit connector and to the slip conduit connector. 21. The method according to claim 20, wherein the electrical conduit is secured to the conduit connector by a fastener threaded into a threaded bore formed in the conduit connector and the electrical conduit is secured to the slip conduit connector by a fastener threaded into said threaded bore formed in the cylindrical member of the slip conduit connector. 22. The method according to claim 20, wherein if the electrical conduit is not visible in the closed-ended slot of the cylindrical member, such non-visibility of the electrical conduit in said closed-ended slot provides a visible warning that a longer electrical conduit is necessary.
