Ordinarily this would be barely worth reporting, but I've had so little to contribute recently that here it is: from the quickly-forgotten series called Megaon Musashi -
In episode #11 of season 2, around the 3:00 mark, a young lady is chained by her wrists to the wall. (She's actually an alien, but most of the time she looks like an earthling.) She's seen in some of the following episodes as well.
In episode #12 of season 2, around the 4:00 mark, another young lady (this time a real earthling) is briefly shown clamped to a chair.
