Review on Green Hanging Snap Hooks: BETOOLL Heavy Duty Swing Hangers For Wooden Sets, Playgrounds, Porches, Indoors, And Outdoors - 2400 Lb Capacity (2Pcs) by David Turner

We had tried multiple ways to attach our swing to a tree branch that sloped upwards. For a few years we had a chain wrapped over the branch; while this worked (until the friction eventually wore through one of the links) it create huge gouges in the branch. We then wen through a series of tree straps all of which frayed and broke - some within days, some within weeks. These have worked perfectly - had to cut 2 small "flat" sections in the branch to screw these to but they have stayed solid for a year now; no more damage to the branch, no straps or chains braking and sending kids sprawling on the ground. Added a little bit of grease to stop some squeaking but other than that perfect.
