A safety plug device disposed in a high-voltage battery to interrupt power supply, the device comprising:

• a female housing including a terminal part;
• a male housing equipped with a fuse and removably coupled to the female housing;
• and
• a grip part slidable on the male housing in forward and backward directions, simultaneously coupled to the male housing in a vertical direction, and equipped with an interlock pin connected to an interlock connector at a rear end thereof,
• wherein the grip part becomes coupled to the male housing and the interlock pin becomes separated from the interlock connector when the grip part is slid forward, to allow the grip part and the male housing to be removed in an upward direction to interrupt the power supply, and
• the grip part includes:
• a grip housing that covers an upper surface and both side surfaces of the male housing;
• and
• a grip pivotably coupled to a front end of the grip housing by a hinge, wherein the grip housing is hooked by the male housing in the vertical direction at a forward position of the grip housing when protrusion parts of the male housing are fitted into coupling slits at the front end of the grip housing.
