Abstract: A hair styling device includes a styling rod and a handle connected with the styling rod, which features a holding device and a pivoting cap connected to the holding device. The cap can be pivoted between an opening and closing position and serves to close the housing for the gas cartridge. The inside of the cap features in the area of its free end contact parts, which are designed to exert, upon closure of the cap, a displacement force on the gas cartridge in axial direction of the device. As a result, by closing the cap, the gas cartridge is moved directly into operating position during which a needle valve is inserted in a valve of the gas cartridge by displacing the gas cartridge. In addition, in the area of its linkage to the holding device, the cap features a clamp which, upon opening of the cap, exerts an axial displacement force on the gas cartridge in longitudinal direction of the device toward the handle's end of the hair styling device and thus brings it into a position of removal.
