Fruit mould consisting of an elongate husk-like body into which a growing fruit is introduced. As the fruit grows, it will assume the shape of the interior of the mould. It is proposed to produce the fruit mould by extrusion. On one side, the husk-like body is open due to the presence of two opposite free ends which can be moved towards each other and away from each other. As growth progresses, a locking device is used to keep these ends together. This locking device is moved to the free ends, preferably by sliding and can also subsequently be removed therefrom. The ends of the resulting fruit are preferably removed, after which the fruit is inserted in a preserving packaging. The invention also relates to a releasing device for such a fruit mould.
