Jaw with semicircular elements (A) for clamping pipes equipped with semicircular adapters (B) that are provided on their concave inner part, near the ends, with two seats (2A), each one of which houses a rotating tooth (A3) hinged into said seat. The rotating tooth (A3) can turn from a position in which it is completely housed inside the seat (A2) to a position in which its free end protrudes outside the seat and faces towards the midpoint of the semicircular element. On its concave inner part the jaw is provided with a groove and each adapter is provided on its convex outer surface with a ridge (B2) complementary to said groove in the jaw. The adapters may be provided on their concave inner part with two seats (B4) with rotating teeth (B5) and a groove (B3), so as to accommodate further adapters with smaller dimensions. <IMAGE> |
