ABSTRACT:
A connection element for light profiles in a sheet pile wall has a base strip (12) for attaching to a component of the sheet pile wall and a hook strip (14) provided at the flat side of the base strip (12) for engaging the interlock (32) of a light profile (30). The hook strip (14) that encloses an inner chamber (16) exhibits a straight connection section (20) that originates at the base strip (12) and runs at least approximately at a right angle to the longitudinal direction of the base strip (12) and a hook section (22) that follows the connection section (20) and runs in an arc-like manner for at least 180°, with the free end of said hook section (22) together with the flat side of the base strip (12) defining a jaw (28). According to the invention, the ratio between the greatest inner width (a) of the inner chamber (16) of the hook strip (14) to the width (c) of the opening jaw (28) is in a range between 2.6 and 2.9.
