A retaining wall comprising a series of differently sized, pre-formed horizontal and vertical blocks. Each block includes a projection and a recess, with the projection and recess arranged and configured so that each projection effectively engages a recess in an adjacent course to operatively connect adjacent courses together. The horizontal, blocks are formed in incremental thicknesses and may be stacked in various combinations equivalent to the height of the vertical, blocks. The location of the abutment member relative to the block may be varied to enable adjacent courses to be coplanar or tiered in a variety of predetermined offset distances.

The apparatus according to claim 1, wherein said at least one portion comprises at least one bar having extremities, the bar extends from said means for guiding plastic deformation at the level of one of said extremities, and wherein the plastic deformation guiding means includes at least one curving template defining at least one curved surface on which the portion undergoing a plastic deformation folds during said deformation. 3. The apparatus according to claim 2, wherein at the level of a contact line between the template and the extremity of the bar extending from said guiding means, the curved surface is tangent to said bar, the curved surface diverging with respect to the bar when seen from the contact line, the convexity of the curved surface being directed towards the bar. 4. The apparatus according to claim 2, wherein the bar has a rectangular cross section and at any point of the curved surface defined by the curving template, the radius of curvature of said curved surface is proportional to the width of the bar measured at the level of a point of said bar in such a way that said point of said bar can come into contact with said point of the curved surface at the time of plastic deformation. 5. The apparatus according to claim 2, wherein the plastic deformation guiding means defines at least two curved surfaces placed on both sides of the bar and symmetrical with respect to a median plane of said bar. 6. The apparatus according to claim 1, wherein material for said at least one portion and said means for guiding the plastic deformation is selected from the group consisting of steels, metal alloys and metal die composites. 7. The apparatus according to claim 1, wherein said at least one portion and said means for guiding the plastic deformation are formed by cutting a metal plate. 8. The apparatus according to claim 1, wherein said at least one portion and said means for guiding the plastic deformation include several identical superimposed single piece elements. 9. The apparatus according to claim 2, wherein said at least one portion and said means for guiding the plastic deformation further comprises at least one support element fixed to at least one template and having one portion of its surface adjacent to at least one bar, said at least one support element being used to limit deformation. 10. The apparatus according to claim 2, wherein said means for guiding the plastic deformation comprises a first and second portion each comprising a curving template and wherein said bar couples said portions, each of the templates defining two curved surfaces placed on both sides of the bar. 11. The apparatus according to claim 2, wherein said at least one portion and said means for guiding the plastic deformation further comprises a plurality of bars placed approximately parallel to one another inside a given plan between two approximately parallel straight lines, the extremities of each of the bars, which are aligned on a first straight line, extend from a first curving template and the extremities of the bars, which are aligned on the second straight line, extend from a second curving template, the two templates being situated inside said plane approximately perpendicular to said bars and each defining a curved surface on both sides of each of the bars. 12. The apparatus according to claim 2, wherein said at least one portion and said means for guiding the plastic deformation further comprises four bars disposed crosswise inside a given plane and approximately perpendicular to one another, four curving templates disposed c
