PROBLEM TO BE SOLVED: To provide a plug lock device capable of surely preventing energization between an attachment plug and a receptacle. SOLUTION: When a blade 3 of the attachment plug 2 is inserted into an insertion hole 12 of the plug lock device 1, a protruded piece 38 is engaged with a bore 4. In the case an insertion lot 14 is positioned at a fixed position inserted in the depth, the tip part 26a of the insertion lot 14 is positioned between a pair of engaging members 18. As a result, even if the protruded piece 38 is going to move in a direction of releasing engagement with the bore 4, since the engaging members 18 are contacted with the tip part 26a and cannot be displaced in the inside direction, the engagement of the protruded piece 38 and the bore 4 is maintained, and the blade 3 is restrained from coming off the insertion hole 12.
