A device for transferring objects, in particular containers such as preforms or bottles, comprising a support (2) which is rotated about an substantially vertical rotational axis and which supports at least one transfer arm (3) with an inner radial part fixed to the support (2) and an outer radial part (6) adapted for sliding with respect to said inner radial part along an elongation axis held within a plane substantially perpendicular to the rotational axis of said support (2), the outer radial part (6) having a gripper head (13) adapted for supporting at least one object, wherein said head (13) is adapted for sliding, with respect to the inner radial part, along an elongation axis substantially parallel to the rotational axis of the support (2).
