Selon l'invention, chacun des éléments de jonction (2, 4) présente une structure en forme de peigne avec des dents de couplage respectives (2a, 4a) définies qui font saillie à partir d'une face (3a, 5a) de l'élément correspondant à assembler (3, 5) qui fait face à l'autre élément à assembler (3, 5) et qui sont disposés côte à côte et mutuellement espacés le long d'une première direction qui est sensiblement parallèle à la face susmentionnée (3a, 5a). Les dents de couplage (2a, 4a) de l'un des éléments de jonction (2, 4) peuvent venir en prise dans les espaces intermédiaires (2b, 4b) qui sont comprises entre les dents de couplage (2a, 4a) de l'autre élément de jonction (2, 4).
