ABSTRACT:
A concrete block having an essentially triangular cross-sectional configuration and an elongate shape and intended to be used to temporarily or permanently delimit roadways, parking lots and the like. The block side faces have a concavely rounded configuration matching that of a vehicle wheel, and the block base comprises bevelled edge faces allowing the block to be tilted at a limited angle upon impact from e.g. a vehicle. An anchoring means of an essentially crank-like shape may be provided to improve the stability of the block, one leg of said crank extending vertically into the foundation whereas the other one projects vertically into a recess formed in the block, said recess having a conical shape to allow tilting of the block upon impact.
