The tongue and groove profiles of the side faces are advantageously wedge-shaped and extend in a substantially axial direction. Such tongue and groove profiles prevent a particular brick from moving in an axial inward movement due to the connection to a neighbouring brick on one side. An axial outward movement is prevented by the tongue and groove connection to a neighbouring brick on the other side. A radial outward movement is also prevented by the substantially axial tongue and groove connection. Finally, a radial inward movement is prevented by the substantially axial tongue and groove connection and by the wedge-shape of the brick. Hence, once a brick is sandwiched between two neighbouring bricks, movement of that brick in any direction is prevented.
