<p>A tamperproof screwing coupling system for valve (102) of a thermal/ sanitary plant for buildings comprises: - a first connecting part (3) and a second connecting part (4) that are mutually couplable through screwing by relative rotation of the first connecting part(3) with respect to the second connecting part (4) around an axis (X) and, - locking means provided on the first part (3) and on the second connecting part (4), arranged to allow such connecting parts to be mutually screwed to a clamping configuration (S), and configured to mutually lock the first connecting part (3) and the second connecting part (4) in the clamping configuration (S), thus preventing a relative unscrewing movement thereof.</p> |
