I suggest starting by distancing yourself emotionally and taking any opportunities to appear busy when they're around. It's important that you also limit your communication with them, since too much contact might make them think that you still care. Additionally, avoid spending time with them like going out for dinner or watching a movie, if you want to further show that you are not interested and could find better company. This could sound callous but it is necessary in order to make sure your needs are met as well. 
Of course, none of this is guaranteed to work but these tactics may help create a stronger boundary between the both of you while allowing space for an eventual healing process.

It is important that you don't express your negative feelings about them being too clingy in an hurtful way, instead use "I-statements" to help them understand how you are feeling. For example, you could say something like:

"When you need to talk to me so often it makes me feel like I am not important and that I don't deserve your time and attention", or "When you grab my hand when we are walking it makes me feel smothered and claustrophobic." This will help them learn the language of emotions without attacking them. You can also explain why these behavior make you feel a certain way and set boundary which they must respect going forward.
