The invention discloses an anti-tightening device cooperatively used with an automobile safety belt, which comprises two fixed plates, a connecting part, a fixed shaft, a pressure mechanism and a moving block, wherein the two fixed plates are respectively fixed at outlets of the automobile safety belt, the connecting part is fixed between the bottom ends of the two fixed plates, the fixed shaft is fixed between the upper sides of the two fixed plates, the pressure mechanism is rotatably arranged on the fixed shaft, the moving block is arranged on the safety belt snap-rabbet in an up-down movable mode, the moving block drives the pressure mechanism to rotate through a tensile wire, and the pressure mechanism can press the automobile safety belt on the connecting part, and the moving block can respectively move upwards and downwards when a safety belt snap-plug is pulled out of the safety belt snap-rabbet and inserted in the safety belt snap-rabbet. When a user pulls out the safety belt and inserts the safety belt snap-plug in the safety belt snap-rabbet, the moving block can move downwards under the action of the safety belt snap-plug, so that the tensile wire is pulled down and drives the pressure mechanism to press the automobile safety belt on the connecting part, so that the discomfortableness produced when the user fastens the automobile safety belt is reduced.
