When ever I see straplock threads, I almost feel too embarrassed to contribute... but the time has come... :oops:
I used to use Schaller many years ago, but found them an absolute pain in the @rse. (I found that after a while they didn't rotate freely on their buttons, they get stuck trying to get them off mid gig, they rattle like buggery, they chew up your guitar lead, and... HORROR! ...ever had the nut undo on the strap during a gig?? :lol:)
I remembered back to the good old days when bread (Mother's Pride, etc) used to have those little plastic things that held the bag shut, instead of sticky-tape... and we used to use those to keep our straps secure... why did bakeries ever stop using free straplocks to secure their bags? :(
And then I found strimmer blades in the early 90s...
Not sure what make they were, but they were something akin to these:

Absolutely perfect for me... :lol:
(I should note, I suppose, that every guitar of mine has its own strap - the only time I have guitar changing trouble is when I buy a new guitar and forget to buy a strap at the same time... :roll:)
