The tooling for performing thermoforming operations, for example, comprises two tool support components articulated by means of a hinge and held in close position by a locking device (9) formed by a handle (12) which pivots about a pin (16) and carries the pivot pin (18) for at least two links (19), each of which is fitted with a hook (20). The path of the pivot pin (18) of the links (19) about the pivot pin (16) of the handle (12) passes through an anti-reversal point obtained by compressing the seal (23) located between the two tool support components. |
