摘要： The invention relates to a fastening system for a sports and recreation device. The fastening system comprises a slackline, two band clamps, and a block and tackle, and two round slings. The fastening system is characterized in that the band clamps and the block and tackle comprise round-sling bolts and slackline bolts, wherein the round-sling bolts and the slackline bolts can be guided in elongated holes and functional holes vertically with respect to their axes and can be displaced, in the direction of their axes, through cut-outs in the functional holes. The bolts, at each of their two ends, comprise bolt heads having a diameter that is smaller than the cut-outs but larger than the elongated holes.
