I own a clash 138 and had the problem of the straps opening all the time, which is annoying. (Search on forums and it seems that its happening to everybody).
But is not a big deal. The board is a awesome :-)
This "small fix" will help clash owners and anybody else that has problems with their straps.
1step: set the straps as you like and feel comfortable.
2step: use a small rope to tie together the tab of the upper part of the strap with the metallic ring on the bottom.
The only problem is that if you want to move the strap again you must untie it. (for instance, if you want to borrow your board to a friend)
Hope its useful.
