ABSTRACT:
A curling iron includes an elongated heating element attached at one end to a handle and having an outer circular peripheral surface provided with a plurality of generally arcuately spaced, radially open grooves extending longitudinally on the outer peripheral surface of the heating element between the first end adjacent the handle and second free end, with the grooves being axially open at the second end. Plurality of bars supporting hair grooming members are slidingly removably engaged in the grooves through the open ends thereof in heat exchange relation with the heating element. An auxiliary handle is attached to the second end of the heating element for preventing removal of the bars from the grooves, there being free, unlimited, bidirectional relative rotation between the auxiliary handle and the heating element. Alternatively, a removable thermally conductive sleeve may be slidably mounted on the heating element and has an inner surface locatable in heat exchange relationship with the heating element and includes at least one tab slidably receivable in one of the grooves through the open end thereof for preventing relative rotation between the sleeve and the heating element. The sleeve also includes, on the outer surface thereof, a plurality of generally arcurately spaced longitudinally extending radially open grooves for alternatively receiving the bars.
