Richco ribbon cable holder, cable holder, CFCC - Clamp, adhesive CFCC-8-04A-RT White PU = 100x1, each 0.09 EUR (Electronics)
Substance to the holders my ribbon cable laid and that worked very well. The holders, however, are of a thin ribbon cable network rather large dimensions - ie there would be still accommodate 1-2 additional cables. Keep with me very well on wallpaper
