Parametric WAGO 221 coupling

I bought a new LG television and unfortunately I had to realize that the power cable is built-in, too short, and equipped with a plug that was too big to push it through the cable duct. So I had to extend the build in cord with an other power cord with a different type of plug. But i wanted something that is not fixed again, like soldering, and with a strain relief for security reasons. This is the result...

It is possible to use more than 2 WAGOs. Just change the value for "clamps".
