Starting things off in episode 3 some stoner named Kong holds two women named Sakura and Ayaka hostage by binding them with flexo cuffs. No idea if he's actually a stoner, but he has the same hat as Jeff from American Dad and I always associate stoners with people that wear that.
Episode 9 has a random girl also getting flexo cuffed (sadly with two guys) because Kamen Rider Evil is a massive dickhead and needs hosts for the Deadmans (the monsters of the week in this series):
As Abomination127 pointed out episode 15 has Aguielra restrained by her wrists and ankles to a chair to be sacrificed to Gifu. She is like this for most of the episode.
Episode 2 of the Kamen Rider Juuga vs. Kamen Rider Ortecta special (why does Toei make so many of these?) has three fake zip tied hostages used by Orteca to trick Juuga into spilling secrets.
Around 8:54. That covers most the DiD scenes from Revice, technically the Live-Evil-Demons epilogue movie has a scene of a girl shackled to a table, but she's too young and I'm not posting that. Kamen Rider Demons' Imperial form looked bad ass enough I was close to swapping avatars with him, not gonna lie.
