what is to be done exactly here?
I am assuming that the ring is to be taken out or something (which actually doesn't make anything for disentanglement tho).Moreover the title of the image is suspicious too.

If everything is like I think it is, it is easy.
Pull the tube out of the hole and place it next to the other tube.
Take the ring, pull it over the small ball, over the piece withe the hole, over the right angle and voilà!

As i said,no entanglement in my view. Ring removal as u say is simple. I still wonder why the image is named murphy's law?
Talking of images,
Grimbal that's quite a avatar u have there, is it all images in a single gif or do you somehow manage to change images at every instant??

I change my mind all the time. 
No, actually, I quickly got bored of any avatar I chose, so I wrote a script that brings back a random picture among those I collected.

In which case, it is not like you think it is!

I do not think it is not the way I think it is.
Actually, I consider it is possible that the pipe going thru the hole is somehow blocked inside. If so, it must be pushed left and right in a way to pass the ring over the piece with the elongated hole and the pipe inside the hole.

The ring is supposed to be removed, th emovign the pipe around and removing the ring the way you said was my first attempt, but I failed there is no way to move the pipe close enough to remove the ring, the rope on it does not provide enough slack.
I have been messing with a real life version of it for hours and have no clue how to remove the ring. I am sure it is possible because someone made it.

Woodwork is one of my pastimes and I've made many, many wooden puzzles; mainly assembly, packing, and disentanglement types. However, I've not seen this one before. Could you clarify if the wooden "pipe", not connected to the section with the slot, is able to slide along the string?
I'll make one when I get a bit of time and have a play with it.
On another note, the website you posted the picture from is amazing – thanks!
It has a massive collection of puzzles:

Maybe you could clarify:
- is the pipe blocked inside the hole?
- is the pipe glued to the rope?
- is the small ball glued to the rope?
- does the ring fit thru the long hole?
- does the large ball fit thru the ring (probably not...)?
(after some thought)
If the replies are no, yes, yes, yes, no, then I think I have a solution.
::- pull the pipe out of the hole.
- push the ring through the hole from the bottom, pass the small ball through the ring and get the ring back through the hole.
- align the small ball with the pierced piece, and put the ring over both the small ring and the pierced piece.
- pull the ring around the corner, over the pipe, along the rope through the hole, and over the small ball.
- the ring should be free.

Sir Col, another similar site, maybe MORE informative-
http://www.johnrausch.com/PuzzlingWorld/default.htm
But you being you, and him being him, you probably know this site already.

The wodden pipes are glued to the rope so they cannnot slide, the pipe does come out of the hole thoguh, because it is not long enough to be stuck in in permanently, I could get a ruler and give you exact deminsions of the objects of my puzzle if you would like.

Then look at my previous post and see the hidden text. Mark the space between the ::'s. Or press ctrl-A.
note: sometime, there are more than one way to do a described action. You'll have to try both.

Thanks for the link, Noke Lieu, but as you guessed, I did know about it already; it is an amazing resource. If you like these types of puzzles, I can thoroughly recommend the book, Cre
ative Puzzles of the World, by Pieter Van Delft and Jack Botermans.
Measurements would be good, Kevin. I'd like to know...
length of each pipe
length of top section
distance from (pipe) end of top section to start of slot
length of string between:
- 1st pipe and 2nd pipe
- 2nd pipe and small ball
- small ball and large ball
I assume that the slot is sufficiently large to pass the ring through with string on one side?
Is the internal diameter of the ring large enough to slide along the top section?
Can the ring pass around the right angle where the 1st pipe meets the top section?
Are you allowed to use a pair of scissors?

Sir Col, I have that book, and also enjoy it. Isn't this puzzle essentially the same as http://www.cubicdissection.com/html/puzcol/disent/ballnring.html? This has no bead stuck in the middle of the string, but that bead may be helpful by keeping you on the right track.

I've got two copies. Well, am in charge of two copies anyway.
Spend much of my time recommending it to teachers. Okay, I meet lots of teachers, and most of them get it recommended by me. It's not exactly much time....

Good spot! It looks like the same principle, if, as I asked above, the ring can pass around the right angle in the wooden version. But I also wondered about the role of the wooden pipes; I felt that their lengths would contribute to restricting movement in some way.

It looks like the same to me.
The woden pipes and the small ball prevent to pass the ring over the angle and the mobile pipe together just like the size of the metal loop prevents to pass the ring over the whole loop.

Most of the time, I find that thinking backwards in a disentanglement puzzle is easier (for me anyway).
So try to imagine the ring already out, and try to figure out a way to put the ring back on. There are 2 ends to the piece, one end with the large ball so the ring can not be removed or put back in thru that end. So it must come off the other end - the block with the hole and the end without the thin rod attached.
I sometimes get a large enough keyring or even a rubber band and try to put that back onto the piece. With a rubber band, you must remember not to cheat by performing a manuever that the metal ring can not do. With a key ring, at least if you get stuck, you can always remove it and start again.
