<p>Safety collar ( 10) for pipe fitting ( T) union ( R), in which the said union ( R) includes a coupling fastened to a pipe ( T) end by means of a nut ( D). According to the invention, the said safety collar ( 10) includes a first and a second brackets substantially U-shaped (10.1, 10.2), which are basically identical and in which the intermediate branch (10.3) of each bracket has a concavity as a circular arc not wider than 180° in a plane substantially orthogonal to the axis of the pipe ( T), while each terminal branch ( 10.4) of each bracket has a through hole ( 10.6, 10.7) in its base, adjacent to the intermediate branch ( 10.3), and a tooth ( 10.5) projecting towards the inside of the ?-shaped bracket at its free end; the holes ( 10.6) drilled in the said first bracket are threaded, while the holes ( 10.7) drilled in the said second bracket allow the threaded shank of a respective screw ( V) to freely pass through and being screwed into the corresponding threaded hole ( 10.6) in- the first bracket.</p> |
