The invention relates to an assembly of several sheet pile walls and at least one pair of connecting profiles (10, 20) with uniform cross section viewed along the longitudinal direction to connect two sheet pile walls (90, 94). In this assembly (100), the first of the two connecting profiles (10) possesses a base attached to the first sheet pile wall (90), a neck strip projecting from the base in a predetermined direction, and a head strip of larger cross section on the free end of the neck strip for engagement with a claw strip partially surrounding the head strip. The second of the two connecting profiles (2) possesses a base attached to a second sheet pile wall (90) and a claw strip to secure a head strip. The head strip of the first connecting profile (100) is thus configured both to secure the claw strip of a sheet pile (94) as a sheet pile wall and to secure the claw strip of the second connecting profile (20), while the claw strip (26) of the second connecting profile (20) serves both to secure the head strip of a sheet pile (94) as a sheet pile wall and to secure the head strip of the first connecting profile (10).
