Abstract
The plastic clip has two clamping members and two spreadable handles, each of which is connected to one of the clamping members, a pivot bearing and a U-shaped compression spring connected between the ends of the handles. The pivot bearing is structured to be assembled by snapping-together. Advantageously the plastic clip is made with polyoxymethylene. Sensor including temperature sensors may be located in the clamping members. A Contact-Reed can be located in one clamping member and a permanent magnet can be located in another clamping member so that unintended loosening of the clip can be detected. The clip may be designed particularly for use as hair clip for a permanent wave treatment.
