A panels set comprising at least two panels, where at least one edge of a first panel (1) has two internal, vertically opposed tongues (9a) which, in use, butt against opposite tongues (9) of a second, adjacent panel (2), the tongues of the adjacent panels being joined by means of a set of internal clamps (4). Preferably the tongues have a seal located on the joining faces, thereby providing a weatherproof seal (5a) when the panels are clamped together. The internal clamps may be spring loaded and are moved from a locked position (Figure 2) to a retracted position (Figure 3) by means of a shuttle (7) and an arm (11) hinged upon a shaft (10). |
