A connection arrangement (10) for connecting perpendicular first and second tubular members (12, 14). The arrangement (10) including coaxial circular and larger square openings (20, 22) provided on opposite faces of the tubular member (12). A circular opening (24) is provided in the second tubular member (14) alignable with the openings (26, 28) further openings are provided in the member 14 on either side of the opening to receive a face of the first member (12) when abutting against the second member (14). A nut (36) is trapped behind the opening (24), and a bolt (38) can extend through the two openings (20, 22) in the first member to engage with the bolt (38) to retain the members (12, 14) together. |

1. A connection arrangement, comprising first and second tubular members, wherein each tubular member is in a respective adjacent plane, the first tubular member having curved end walls extending longitudinally along of the first tubular member and spaced apart by inner and outer faces of the first tubular member, a first opening in said outer face of the first tubular member effectively sized to receive a male fastening member therethrough, a second opening being provided on the inner face of the first tubular member opposite the first opening, the second opening larger than the first opening, and being at least generally rectangular, a third opening being provided in an inner face of the second tubular member facing the first tubular member, which third opening is alignable with the first and second openings to engagingly receive the male fastening member, and fourth and fifth openings in the inner face of the second tubular member located on opposing sides of a mounting part of the second tubular member that is defined between said fourth and fifth openings, which mounting part comprises the third opening therein, wherein sides of the fourth and fifth openings adjacent and defining said mounting part being at least generally straight sides such that the mounting part is adapted to be slidingly received in the second opening, whilst the respective opposite sides of the fourth and fifth openings are curved so as to each receive a respective curved end wall of the first tubular member engaging thereagainst. |
