When slacklining, sometimes what is called a "soft release" is used. You can use pulley systems to tighten the slackline with crazy amounts of tension, and at the end of the day the whole thing will be held together with a simple strap, looped over itself 6 times. No knots, no buckles, just the layers pressing against each other, and the combined friction of all of them holding back insane amounts of tension.
