The joining device serves for connecting two adjacent individual elements ( 5, 11 ) of a sheet pile retaining wall which are to be pile-driven in each case, e.g. for connecting two adjacent pipes of a sheet piling. The first joining element comprises a button strip ( 9 ) which is received in a hollow space ( 15 ) between two hook strips ( 14 ) of a second joining element ( 2 ). In order to be able to better absorb tensile forces occurring during driving, the first joining element ( 2 ) comprises holding portions, e.g. holding strips ( 16 ) which at least partly encompass the hook strips ( 14 ) of the second joining element ( 3 ) and thus prevent a widening of the hook strips during driving.
