Half-portion (1) for moulding a plastic container (2), comprising:
a support (4) and a half-mould (3) which is fastened to the support (4) through:
a first set of protruding elements (6a) screwed in corresponding seats of the support (4) for striking on the half-mould (3);
a bracket (8) placed external to the support (4) and from where a second set of protruding elements (6b) branches off so that the rotation of the bracket (8) causes the insertion of the protruding elements (6b) in through-cavities (7) obtained in the support (4) in such a way as to strike on the half-mould (3) and block it;
a clamping element (12) to block the rotation of the bracket (8).
