ABSTRACT:
A connection element for connecting a sheet pile to a carrier element, with a base strip (16) to be fastened to a carrier element (14), is provided with an interlock profile (20) for engaging the sheet pile (14). The interlock profile (20) exhibits a lock chamber (28) that is defined by the base strip (16), a support strip (24) that protrudes from the base strip (16) and a hook strip (26) that protrudes from the base strip (16), whereby the hook strip (16) exhibits a straight extending transition section (32) protruding from the base strip (16) and a hook section (34) that follows said transition section and points in the direction of the support strip (34). The hook section exhibits a first support surface (26) that faces an inner surface (30) of the support strip (24), whereby the first support surface (36) and at least that section of the inner surface (30) of the support strip (24) that directly faces the first support surface (26) are located in parallel converging planes (E1, E2) and together define the jaw (42) of the lock chamber (28). The first support surface (36) transitions under an acute angle (α) into a second support surface (38) that defines the lock chamber (28).
