<p>The detachable panel has profiled strips along opposite edges, by which it is secured to others. One strip is shaped so as to form a boss (10) whose surface is flush with that (0') of the panel itself when seen in cross-section, with a clamping hook (100) below and protruding beyond the boss. The hook engages below a boss (20) on the adjacent panel and which forms a step below the surface of the latter, and in a portion (200) between stops (201', 201"), so that the bosses overlap and some sliding movement in their lengthwise direction is possible.</p> |
