Patent ID: 7857551

Claim:
A connection element with a uniform cross-section for connecting a sheet pile to a carrier element, with a base strip having two sides, which is adapted to be fastened on one side to the carrier element and which is provided with an interlock profile on an opposite side for engaging the sheet pile; wherein the interlock profile exhibits a lock chamber that is defined by the base strip, a straight support strip that protrudes outward from said opposite side of the base strip and a curved hook strip that protrudes outward from said opposite side of the base strip, whereby the hook strip exhibits a straight extending transition section protruding from the base strip and a hook section that follows said transition section and points in the direction of the support strip; wherein said hook section exhibits a first support surface that faces an inner surface of the support strip, whereby the first support surface and at least that section of the inner surface of the support strip that directly faces the first support surface are located in parallel planes (E 1 , E 2 ) and together define the jaw of the lock chamber; wherein the first support surface transitions under an acute angle (α) into a second support surface that forms a part of the lock chamber; wherein the acute angle (α) between a plane (E 3 ), in which the second support surface extends, and the plane (E 2 ), in which the first support surface extends, exhibits, in a cross-sectional view, a value in the 40 to 50° range, and wherein, in a cross-sectional view, the length of the first support surface and the length of the section of the inner surface that directly faces the first support surface both correspond at least approximately to the length of the second support surface.
