A tool securing plate assembly with adjustable and replaceable tool securing means including inter-connected tool securing plates, retaining strips, and elastic bands. The tool securing plates are provided with arrays of spaced round through holes. The elastic bands are secured to the tool securing plates by means of the retaining strips. The retaining strips include projections at both sides for engaging the round through holes, a projecting block disposed in the middle for pressing against the elastic band, and a triangular non-skid tooth at the middle of the projecting block for pressing the elastic band deeper into the round through holes so as to firmly secure the elastic bands on the tool securing plates. The elastic bands are adjustable at one end. The tool securing plate assembly can be adapted for use in tool kits or bag type tool kits or suspended on the walls.
