A screw hiding device for combining lateral tubes with upright tubes includes a position strip to match with each lateral tube. Each position strip has an upright wall to contact with each upright tube and fixed together with a screw. Each lateral tube has plural holes for the upright tube to pass through, and a lower support ridge at two sides of each hole and two upper stoppers respectively on two opposite inner walls, with the distance between each upper stopper and each lower support ridge being equal to the height of the upright wall of the position strip. Each position strip is fixed on an outer surface of each upright tube with a screw and in the space between the upper stopper and the lower support ridge, with each lateral tube hiding each screw and each position strip to beautify a fence formed by the lateral and the upright tubes.
