The present invention relates to a foolproof interlock apparatus, adapted to enable a first device to interlock with a second device, which comprises: at least a hook, composed of an extending part and a engaging part; and at least a lip having a recess; wherein, the engaging part is disposed at a free end of the extending part while an end of the extending part is fitted to the first device; and the recess of the lip fitted to the second device is used to receive the engaging part for enabling the recess and the engaging part to abut against each other and thus maintain a specific engagement. Therefore, by adjusting the engagement between the hook and the lip, the tightness of the engagement between the first and the second device can be controlled.
