PCT No. PCT/AT86/00064 Sec. 371 Date Jun. 10, 1987 Sec. 102(e) Date Jun. 10, 1987 PCT Filed Oct. 10, 1986 PCT Pub. No. WO87/02540 PCT Pub. Date Apr. 23, 1987.In an electrical surface heating element, there are conductors (10) embedded within a panel (1) of electrically insulating material, which conductors are connected to supply conductors or, respectively, to the heating conductors of the surface heating element, and enter cavities (7) of the panel (1) open to the panel edge (6), within which cavities the electrical connecting points for connecting adjacent panels (1) are located. Each cavity (7) is constricted in direction towards the panel edge (6) and can be closed above by at least one removable cover (15,16), so that the connecting points of the conductors (10) are accessible also after having installed the panels (1). |
