1. A kit for a retaining wall comprising:
- at least two molded blocks adapted to be placed in a keyhole overlying position one to the other, each block having top, bottom, front, rear, and end faces, wherein the top and bottom faces are parallel, an opening extending into one of the blocks from one of the top, bottom, and end faces and parallel to the rear face, the key hole opening including a narrow slot extending toward the rear face,a retaining member adapted to be inserted into the opening, the retaining member including a stem portion to be fitted into the opening, and a narrow shank portion projecting partly in said slot and beyond one of the top and bottom faces, the shank having an abutment portion which is parallel to the rear face, the abutment portion of the shank portion being adapted to engage a rear face of the other of the blocks to retain the one block in relation to the other.

Abstract
A retaining wall kit is made up of a plurality of molded blocks, some having different thicknesses and some having different lengths. Keyhole-slots may be provided at the rear face of the molded blocks, each keyhole being proportionally sized inwardly of the rear face of the block such that a retaining member fitted within the keyhole-slot projects downwardly from the one molded block to engage the rear face of an adjacent molded block so as to space the molded blocks in a regular sloped position such that the inter section of the front and top faces of each molded block is in a common plane.

13. A kit for assembling a retaining wall, wherein the kit comprises a predetermined number of concrete blocks, each block having parallel top, bottom, front, and rear faces, an X-axis in a longitudinal direction which is parallel to the front and rear faces, a Y-axis perpendicular to the X-axis, and a Z-axis perpendicular to the X- and Y- axes,
wherein all of the blocks have equal dimensions along the Y-axis, at least two blocks have different dimensions along the X-axis, and at least two blocks have different dimensions along the Z-axis, wherein the kit also includes retaining members for use with adjacent blocks when the wall is being staggered to form a slope with an intersection of the top and front faces lying in a common plane, wherein the slope of the plane is between 0° - and 45°
from a vertical direction, and the retaining members is spaced from the rear face by a distance determined from the dimension of the blocks along the Z-axis. - View Dependent Claims (18, 19)
