how to enclose connections on low voltage transformer

I am installing low voltage lights in a cabinet. The transformer (12v v magnetic) is simply a black unit 3 inches by 6 inches with a set of black and white wires on 1 side (120v), and two white wires on the other end (12v).
I would assume that the 120v connections (to romex) must be in a junction box. How would you place them in a box? Normally, romex is clamped by the little clamps in the box, but these wires are unsheathed.

Can you be more specific? If there is a cord attached to the transformer that was installed by the manufacturer then what does the manufacture recommend? If this is some thing that you did what exactly did you do and what did you use to do it with? Is the point with the black and white wires threaded with the wires through the middle? we need more info to be able to help.

Is it something like this one?

If so, the line voltage wires are pretty thin and a clamp won't hold them. Use a plastic j-box and run them thru a different hole than the input (line) wires. The transformer itself sits outside the box. Secure it such that it isn't putting any tension on the wires. The wirenut connections on the low voltage side don't need to be in a box.

actually, this is the exact transformer:

would you recommend the plastic junction box as in the earlier post?

I was going to wrap the wires with heat shrink tubing.

Post Follow the instructions

In the instructions on the website, the manufacturer states this.....
" To comply with electrical code line voltage connections and transformer should be enclosed in a junction box ( not included)."

Texsparky is correct the whole thing needs to go inte a large junction box or a trough.

You need to use one of these:

The manufacturer specifically recommends this box under "Options/Accessories" on the spec sheet:
