Abstract: An apparatus or clip is disclosed, which can be used both to securely hold and support a heating cable or mat at a desired depth within a slab form, and to easily locate the cable or mats once embedded using a simple magnetic field. The clips of this invention are constructed from a material that has a suitable magnetic susceptibility for permitting detection by a weak magnetic field. Consequently, the clip can be located using a simple bar magnet or a common stud finder. The high magnetic permeability of the clip compared to the surrounding earth, asphalt or concrete allows the clip to be readily located by a stud finder. As a stud finder is passed over the clip, the magnetic needle is attracted to the clip apparatus by the emitted magnetic flux. The configuration of the clip includes two upright legs and two horizontal feet. The legs are bent to support and space the mat or cable above the feet.
