I would imagine you'd accomplish this by placing a "bond" between i and k.
You can then set the value of this bond force constant (which is a harmonic
interaction) in the frcmod when you load it into leap. You can use the
"bond" command in leap, just make sure that you have the appropriate
parameters available.
Good luck!
