Each joint component (8,9) comprises a base part (11,12) which locates against the wall in which it is fixed by anchoring units (2). The base part evolves along its one long edge into an edge part formed with an inwardly open groove facing the wall. The joint components are fitted with edge parts extending along one another. The U-shaped seal (10) has its two legs inserting into each of the grooves. |
