<p>The inventive breaker bar comprises a curved handle (1) which is articulated on two fixing mechanisms (21, 31; 22, 32) fixing said curved handle (1) on a support. Each fixing mechanism consists of on expandable pin (21, 22) and a stud (31, 32) which engages in said expandable pin and can move between a first idle position and a second position in which it causes the pin (21, 22) to expand. The curved handle (1) of the breaker bar is arranged in such a way that it can be pivoted so as to bump the pins (21, 22) and cause them to move from their first position to their second position.</p> |
