Hair styling iron having interchangeable heating tips

An elongated handle having a square cross-section is adapted at one end to receive a swivel electrical power supply means and at the other end to receive a detachable hollow, metal housing which encloses a heating element. The housing is elongated about its longitudinal axis and is formed with a plurality of flat side surface portions disposed angularly with respect to each other and joined at parallel edges which are slightly rounded for imparting a temporary bend to wet hairs held over the rounded edges under tension. A flipper arm type hair holding means is pivotably mounted to the handle and has a blade portion which overlies the upper flat side surface of the housing for sandwiching strands of hair therebetween. The housing and handle are coupled together through quick-release, locking means operable with the same hand with which the handle is held by simply depressing a release button mounted on the handle permitting an urging means to disconnect the housing from the handle without the necessity of the operator to use the other hand to touch or grab the hot housing. Means are provided for applying oil vapor to the held hair through slots on the upper flat side surface of the housing.
