The shaping pliers for connecting copper tubes has a cap with a plastic plug (4), an axial stop (3) and a shaft (5) extending through the plug to actuate the stop for movement towards the plug. A linkage exerts a traction force on the shaft opposite to a hole formed in a washer (11) surrounding the shaft. The linkage has a handle with a cavity receiving the washer and a piston sliding in the cavity. The piston is moved by a lever hinged on the handle. |
