    Abstract: The invention relates to a device for gripping a container preform having a base, a spindle which is mounted on the base, and an ejector at least partially surrounding the spindle. The spinner includes a spindle mounted such that it pivots in a sliding manner in relation to the base and a spinner tip removably fixed to the spindle. The ejector partially surrounds the spinner and is able to occupy a working position in which it is secured to the base. The spinner tip and the ejector are respectively provided with an imprint and a complementary counter-imprint. The ejector can be removed from the base and can occupy a tooling position in which the counterpart thereof cooperates with the cavity of the spinner tip so that they rotate together.
