Abstract: A U-shaped connector bracket connects an end of a first tubular frame member to a second frame member having two opposite sides and a pair of elongate recesses respectively located in and extending along the two opposite sides. The connector bracket has a pair of side arms, an end member extending between a first end of each side arm at a dependent end of the bracket, and projections at a second end of each side arm that are directed inwardly towards one another. The dependent end of the connector bracket is adapted for insertion within the end of the first tubular frame member. The projections from the side arms secure the connector bracket to the opposite sides of the second frame member by being located within a respective recess of the second frame member.
