pinhole leak in black mainline

I've found a soggy spot in my yard, figured the main was leaking. Yup, it is a black plastic (polyethylene or pex??) about 1" OD pipe and there is a pinhole leak in it. I have the leak exposed and about 6 inches under it and a foot on either side of it. Now, i have no idea how to fix it. Can I patch it somehow? my father in law talked about using a milk carton and melting it on there... what should i do?"

Repair

Uncover an additional foot on each side. Cut the pipe directly on the pin hole. Remove an additional 1/4" of pipe from either side. Purchase a 1" poly insert coupling and two stainless steel clamps. Exposing more of the pipe will give you the flexability to pick the ends up far enough to insert the coupling, being sure to install the clamps first.
