The wall is adapted to accommodate the nut on a split bolt connector in the aperture and the at least one tab, or the member, is adapted to engage the slot in the split bolt after the nut is connected to the split bolt. ## Claims ### Claim 1 A retaining device for a split bolt connector assembly, wherein the assembly includes a nut having a plurality of flats and a split bolt having a bolt head, a threaded end, a mid-portion and two cantilevered legs extending away from the bolt head which define a slot between the legs, wherein the slot extends from a base located in the mid-portion to an opening at the threaded end and wherein the slot defines the legs as independent structures between the base and the threaded end, the retaining device comprising: a continuous wall defining an aperture and having an interior surface and an exterior surface; and at least one tab extending upwardly from the wall, wherein the wall is adapted to accommodate the nut in the aperture and the at least one tab is adapted to engage the slot in the split bolt. ### Claim 2 (depends on 1) The retaining device of claim 1, wherein the wall comprises a plurality of adjoining wall sections. ### Claim 3 (depends on 2) The retaining device of claim 2, wherein the plurality of adjoining wall sections are substantially flat and correspond to the flats of the nut. ### Claim 4 (depends on 1) The retaining device of claim 1, wherein the at least one tab is bendable. ### Claim 5 (depends on 1) The retaining device of claim 1, wherein the wall comprises from four to eight adjoining wall sections. ### Claim 6 (depends on 5) The retaining device of claim 5, wherein every second adjoining wall section has a tab extending upwardly therefrom. ### Claim 7 (depends on 1) The retaining device of claim 1 further comprising one or more ribs extending inwardly from the interior surface of the wall. ### Claim 8 (depends on 2) The retaining device of claim 2, wherein the plurality of adjoining wall sections are connected by a plurality of corners. ### Claim 9 (depends on 2) The retaining device of claim 2, wherein the adjoining wall sections are disposed in relation to each other at an angle of 45, 60 or 90 degrees. ### Claim 10 (depends on 1) The retaining device of claim 1, wherein the wall and the at least one tab are formed from a malleable metal. ### Claim 11 A retaining device for a split bolt connector assembly that includes a split bolt and a nut having a plurality of flats, wherein the split bolt has a bolt head, a threaded end, a mid-portion and two cantilevered legs extending away from the bolt head which define a slot between the legs, wherein the slot extends from a base located in the mid-portion to an opening at the threaded end and wherein the slot defines the legs as independent structures between the base and the threaded end, wherein the retaining device comprises: a continuous wall having an interior surface, wherein the wall defines an aperture; and at least one tab extending upwardly from the wall; wherein the wall is adapted to accommodate the nut in the aperture so that the interior surface corresponds and is in close proximity to the plurality of flats and the at least one tab is bent into the slot to engage the split bolt after the nut is connected to the split bolt. ### Claim 12 (depends on 11) The retaining device of claim 11, wherein the at least one tab is bendable. ### Claim 13 (depends on 11) The retaining device of claim 11, wherein the split bolt has a slot and wherein the at least one tab is adapted to engage the slot. ### Claim 14 (depends on 11) The retaining device of claim 11, wherein the continuous wall comprises from four to eight adjoining wall sections and from two to four tabs. ### Claim 15 (depends on 11) The retaining device of claim 11, wherein the continuous wall is comprised of six adjoining wall sections and three tabs. ### Claim 16 (depends on 14) The retaining device of claim 14, wherein the adjoining wall sections are substantially flat and the length of the wall sections is substantially the same. ### Claim 17 (depends on 16) The retaining device of claim 16, wherein the distance between the substantially fiat, exterior surfaces of opposing wall sections is ⅜, 7/16, ½, 9/16, ⅝, 11/16, ¾, 13/16, ⅞, 1, 1¼, 1½, 1¾ or 2 inches or from 10 mm to 50 mm. ### Claim 18 A retaining device for a split bolt connector assembly, wherein the assembly includes a nut having a plurality of flats and a split bolt having a bolt head, a threaded end, a mid-portion and two cantilevered legs extending away from the bolt head which define a slot between the legs, wherein the slot extends from a base located in the mid-portion to an opening at the threaded end and wherein the slot defines the legs as independent structures between the base and the threaded end, the retaining device comprising: a continuous wall defining an aperture and having an interior surface and an exterior surface; and at least one tab extending upwardly from the wall, wherein the retaining device is installed on the nut after the nut is secured to the split bolt, wherein the wall is adapted to accommodate the nut in the aperture so that the interior surface corresponds and is in close proximity to the plurality of flats and wherein the at least one tab is adapted to engage the slot in the split bolt. ### Claim 19 (depends on 18) The retaining device of claim 18, wherein the wall comprises a plurality of substantially flat adjoining wall sections connected by a plurality of corners. ### Claim 20 (depends on 18) The retaining device of claim 18, further comprising one or more ribs extending inwardly from the interior surface of the wall.
