JQuery – Add css class to List

I have the following HTML :

<li>
<a class="meuble-tab" href="#">Meuble</a>
</li>

i need to achieve the following:

<li class="active">
<a class="meuble-tab" href="#">Meuble</a>
</li>

Using Jquery I am at the point where i can get to the

$(“.meuble-tab”)

How do I get to its parent “li” to do the addClass(“active”)?
