The present invention relates to a waterproof electric plug with fuses that comprises a housing, a fuse holder, a fuse cover, two plug blades, two tubular fuses, and power lines. When the cover and the holder are inserted into the housing, the complicated structure that is formed will prevent any water or liquid from entering into the housing and the holder. The cover can be pushed to expose an opening in the housing through which the tubular fuses can be replaced.
