The present invention provides a locking device for a folding door. The locking device for a folding door includes: a handle unit installed in a door frame; and a locking unit connected to the handle unit and locking a folding door according to an operation of the handle unit. The handle unit includes: a body fixed to the door frame; a handle supported on the body to be rotated; a square bar connected between the handle and the locking unit and operating the locking unit when the handle is rotated; and an elastic member installed in the body and elastically coming into contact with the side of the square bar to maintain a rotated position of the handle. The locking device for a folding door prevents the handle from returning to an initial position, thereby maintaining a locked position of the folding door and an unlocked position. |
