A fixing device for moulds for plastic articles, where a pair of half-moulds ( 3, 4 ) in which a force plug ( 11 ) can be inserted, comprises at least one tie rod ( 6 ) for keeping the two half-moulds in a closed position, the said tie rod being hinged, at one end, to the mobile half-mould and having a second end of a hammer-headed shape which hooks to two gripping jaws ( 60, 61 ). The tie rod ( 6 ) is hinged to a connecting rod which rotates on a pivot fixed to the resting base ( 14 ), which, in the movement of rotation, sets the tie rod ( 6 ) along the line corresponding to the centroid of the pressure forces produced during the moulding operation.
