Abstract
The wall contains elongate members (1) which are connected to one another by means of junction pieces (2). Each member (1) has a tubular portion (7) and at least one endpiece (10). That part (12) of the endpiece (10) located outside the portion (7) is equipped with a gripping wheel (30) for making and breaking the connection between the elongate member (1) and the junction piece (2). The junction piece (2) contains a baseplate (40) with receiving parts (41) for the endpiece (10) of the member (1) and a device (65) which makes it possible to fasten further wall components (3,9,71) to the junction pieces (2). The receiving part (41) comprises cheeks (42,43), between which extends an axle (45). A slot in the gripping wheel (30) surrounds this axle (45) when the endpiece (10) is located in the receiving part (41). The baseplate (40) is equipped with orifices (83) which allow the connection of wall plates (3,4) and hinges (90).
