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 {umlaut over (&ngr;)}-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. |
