A modular wall block is adapted for being assembled together with a number of other blocks in stacked courses to form a retaining wall. The wall block has a front and rear, top and bottom, and opposing sides. At least one of the opposing sides defines a generally L-shaped vertical slot. A course connector is received in the vertical slot, and includes first and second ends joined together by a setback spacer. The firs t end extends in an x-direction and a y-direction, and defines a generally L-shaped structure received in the L-shaped slot and restricting forward, rearward, and outward movement of the course connector. The second end of the course connector extends outwardly in a z- direction beyond one of the top and bottom of the wall block to engage one of the numb er of other blocks in an upper or lower course. The setback spacer locates the second en d of the course connector a spaced distance from the first end to position the wall block in the retaining wall relative to the other blocks in the upper or lower course.</S DOAB>
