Two identical connector pieces with a middle part, arms, profiles and coupling members are fitted together to form corner joints. The joint is formed by one or more connector pieces (1) that comprise a middle part (10) and at least two arms (11a,11b), the arms being provided with profiles (13a-13d). A second identical connector piece is positioned at distance from the first connector piece, and like the first piece is provided with coupling members to enable the two pieces to be fixed together. Independent claims are included for (a) the connector pieces, and (b) coupling members used in the above corner joints and connector pieces.
