         3 . An assembly as claimed in  claim 1 , said assembly comprising a fourth block, wherein the protuberance comprises a tongue extending under the entire external face of the protuberance, this tongue having a stepped profile with a width less than the width of said protuberance so as to be able to be inserted in the opening in another block in the assembly.  
     
     
         4 . An assembly as claimed in  claim 1 , said assembly comprising a fifth block, wherein the tongue extends over half the length of the protuberance at the base of the block.  
     
     
         5 . An assembly as claimed in  claim 1 , said assembly comprising a sixth block, wherein said sixth block is solid and comprises a tongue which extends over substantially half the length of the external face of the protuberance.  
     
     
         6 . An assembly as claimed in  claim 1 , said assembly comprising a seventh block, wherein said seventh block is solid and comprises a tongue which extends over the entire length of the external face of the protuberance.  
     
     
         7 . An assembly as claimed in  claim 1 , said assembly comprising an eighth block, wherein the tongue on the protuberance comprises two lateral parts on each side of a central part, the lateral parts having substantially identical thicknesses and the central part having a thickness substantially equal to that of the protuberance itself and said lateral parts and the central part of the tongue extending longitudinally as far as approximately half the external face of the protuberance.  
     
     
         8 . An assembly as claimed in  claim 7 , said assembly comprising a ninth block, wherein the lateral parts and the central part of the tongue extend over the entire length of the external face of the protuberance.  
     
     
         9 . A building construction block as a component of the assembly as claimed in one of  claims 1  to  8 , wherein the protuberance situated at the base of the splayed U has a thickness (h p ) substantially equal to at least one fifth of the height (h T ) of the longitudinal wall of said construction block.  
     
     
         10 . A construction block as a component of the assembly as claimed in any one of  claims 1  to  8 , wherein the protuberance has a width equal to at least two thirds of the width of the transverse side of the construction block.  
     
     
         11 . A construction block as a component of the assembly as claimed in any one of  claims 1  to  8 , wherein the opening in the form of a splayed U extends over at least 50% of the height of said construction block.  
     
     
         12 . A construction block as a component of the assembly as claimed in any one of claims I to  8 , comprising a drainage hole disposed at the bottom of the block at one end of said block, the hole passing right through the base of the block from the top internal face of the base to the external face of the base and the internal face of the block having a slope whose bottom part is situated level with the drainage hole.  
     
     
         13 . A construction block as a component of the assembly as claimed in  claim 12 , wherein the drainage hole is disposed at the centre of the base of the block, the bottom part of the slope of the internal face of the base of the block being situated level with said drainage hole.  
     
     
         14 . A construction block as a component of the assembly as claimed in any one of the preceding claims, wherein the length of the block is substantially equal to twice its width and said length is also substantially equal to twice the height of the block.  
     
     
         15 . A construction block as a component of the assembly as claimed in any one of the preceding claims, wherein the length of the block is substantially equal to its width and to its height.  
     
     
         16 . A construction block as a component of the assembly as claimed in any one of the preceding claims, characterised in that it consists of a material chosen from amongst concrete and terracotta.

         18 . A joint for a construction block as a component of the assembly as claimed in  claim 1 , arranged to be disposed between two blocks of the assembly as claimed in any one of  claims 1  to  16 , the profile of the joint being traced on the lateral profile of the blocks between which it is disposed, the width of the said joint being less than that of the lateral profile of the blocks between which it is disposed, said joint being thus arranged to be inserted in the opening in another block disposed staggered under the two blocks.  
     
     
         19 . A joint as claimed in  claim 18 , made from a resilient material chosen from amongst polystyrene and Neoprene®.  
     
     
         20 . A mould for forming at least two building construction blocks, the mould comprising at least a first sequence of cells and at least a second sequence of cells substantially in the form of a U disposed so that the first sequence of cells and the second sequence of cells are disposed straddling one another.  
     
     
         21 . Use of the mould as claimed in claim  20 , for forming building construction blocks as a component of the assembly as claimed in one of  claims 1  to  8 .
