and at least one complementary locating member forming a channel for locating a peg member therein on each of the first and second sides of the wall member; wherein the locating members comprise a U-shaped member having a first side integrally moulded with a side of the wall member, a second side opposed to the first side, a back face and an open front face and wherein the locating member further comprises a tab integrally moulded with at least one side of the U-shaped member and extending across the open front face of the locating member and the back face has a cut out section opposed to the tab and of a least the same dimensions as the tab. ### Claim 2 (depends on 1) The box of claim 1 wherein the locating members each comprise a channel of square or rectangular cross-section. ### Claim 3 (depends on 1) The box of claim 1 wherein the tab is integrally moulded with both sides of the U-shaped member. ### Claim 4 (depends on 1) The box of claim 1 wherein the tab extends part way across the front face of the U-shaped member. ### Claim 5 (depends on 1) The box of claim 1 wherein the cut out section in the back face of the U-shaped members is larger than the tab. ### Claim 6 (depends on 1) The box of claim 1 wherein the peg members each comprise an elongate rigid member that extends through a plurality of locating members. ### Claim 7 (depends on 6) The box of claim 6 wherein the locating members further comprise peg retaining members. ### Claim 8 (depends on 7) The box of claim 7 wherein the peg retaining members comprise one or more ridges integrally moulded in the interior of the locating members. ### Claim 9 (depends on 7) The box of claim 7 wherein the peg members each comprise a plurality of cross pieces that coact with the peg retaining members to hold the peg in the locating members. ### Claim 10 (depends on 9) The box of claim 9 wherein the peg members each comprise two side pieces and a plurality of cross pieces at right angles to the side pieces. ### Claim 11 (depends on 9) The box of claim 9 wherein the peg members each comprise two side pieces and plurality of cross pieces forming triangles between the side pieces. ### Claim 12 (depends on 1) The box of claim 1 wherein one or more of the panels further comprise a plurality of complementary locating members on the top and bottom of the wall member. ### Claim 13 (depends on 1) The box of claim 1 wherein the peg members are moulded from plastics material. ### Claim 14 (depends on 1) The box of claim 1 wherein the panels are moulded with one or more removable sections. ### Claim 15 (depends on 1) The box of claim 1 wherein the panels are moulded in two sections, an outer section forming a wall member having a hole through the front to rear faces and including retaining elements, and an inner section which is located in the hole in the outer section by the retaining elements in the outer section. ### Claim 16 (depends on 1) The box of claim 1 wherein the one of the panels comprises a base panel. ### Claim 17 (depends on 1) The box of claim 1 wherein the panels further comprise base retaining members and the box further comprises a base panel. ### Claim 18 (depends on 1) The box of claim 1 further comprising a lid. ### Claim 19 A pole mounting access chamber comprising a box having a plurality of panels moulded from plastics material and a plurality of peg members, each panel comprising: a wall member comprising a front face, a rear face, a top, a bottom, a first side and a second side; and at least one complementary locating member forming a channel for locating a peg member therein on each of the first and second sides of the wall member; wherein the locating members comprise a U-shaped member having a first side integrally moulded with a side of the wall member, a second side opposed to the first side, a back face and an open front face and wherein the locating member further comprises a tab integrally moulded with at least one side of the U-shaped member and extending across the open front face of the locating member and the back face has a cut out section opposed to the tab and of a least the same dimensions as the tab. ### Claim 20 (depends on 1) A method of assembling the box of claim 1 comprising steps of: locating a first panel adjacent a second panel, such that the locating members on the first side of the first panel are arranged alternately with the locating members of the second side of the second panel; and inserting a peg member through the peg locating means of the locating members to hold the panels rigidly together. ### Claim 21 A box panel moulded from plastics material, comprising: a wall member comprising a front face, a rear face, a top, a bottom, a first side and a second side; and at least one complementary locating member forming a channel for locating a peg member therein on each of the first and second sides of the wall member; wherein the locating member comprises a U-shaped member having a first side integrally moulded with a side of the wall member, a second side opposed to the first side, a back face and a an open front fact and wherein the locating member further comprises a tab integrally moulded with at least one side of the U-shaped member and extending across the open front face of the locating member and the back face has a cut out section opposed to the tab and of at least the same dimensions as the tab.
