A release mechanism is provided ensuring simultaneous opening of the two clamps of a traction apparatus for freeing the cable which passes therethrough. The release lever is mounted for longitudinal sliding by actuation of the handle while moving the intermediate pin carried by the warping out lever. A pivoting bolt, mounted in a widened end of a longitudinal oblong slit of said lever, prevents the release movement. The release can only be obtained when the user frees said bolt with one hand against the return action of a spring and, with the other hand, operates simultaneously said handle. |
