Abstract
A tool with two elongated handles and two jaws operatively connected to the handles is provided with a mechanism for preventing premature opening of the handles and jaws. The mechanism comprises a pawl operating as a bistable rocker and engaging, with one or with two engagement means, an engagement member defined by two projections delimitating an operational area, or by at least one row of teeth with which each of the two engagement means is alternately engageable, so as to prevent premature interruption of the closing movement and preferably also of the reverse opening movement of the handles and of the jaws.
