ABSTRACT:
An adapter for pipe locking clamps, particularly but not exclusively useful for welding portions of plastic piping by polyfusion. The adapter has at least two bodies obtained from a metal plate, and arranged parallel to each other. The bodies have respective circular arc-like lateral rims that have a same radius of curvature. The centers of curvature of the circular arc-like lateral rims are all arranged on a same axis so as to form a partially cylindrical concave surface forming an open cradle which is adapted to lock the pipes in cooperation with a similar surface formed on a complementary and opposite reduction unit.
