Abstract: Transfer star-wheel (1) for containers (100) of thermoplastic material, comprising: a rotary carousel (2) bearing a plurality of supporting stations (S) for supporting containers (100) by their neck (100b), in each supporting station (S) being provided a pliers (3) hinged to the rotary carousel (2) at a hinge axis (AA) in such a way that it assumes at least a first configuration in which the pliers (3) is fixed, that means it cannot rotate about its hinge axis (AA), and a second configuration in which the pliers (3) can oscillate about its hinge axis (AA); a cam kinematic motion that is operatively active on each pliers (3) for maintaining it in the first configuration, characterized in that it comprises a reactivating device (8) for each pliers (3), that comprises elastic means (9, 10) operatively active on the pliers (3) to bring it from the second to the first configuration following an accidental event that deactivated the pliers.
