They are also used for jib sheets on small sailboats. Each clip resembles a link of chain, with a split through one side. The edges of this split are chamfered, so that the clips can be engaged or disengaged, but only if they are carefully aligned by hand. When pulled tight, the links are securely fastened, although they allow a quick release if needed. There are no moving parts to the link. Personally, I use a pair of sister clips for a quick attach and release of the outhaul retraction bungee on my Laser sailboat (for that purpose, print a pair of two scaled down version [80%] of the "small" clip - file "Sister_clips_small.stl"). The clip is quite strong, but bear in mind: it is PLASTIC !!! DO NOT USE FOR SAFETY EQUIPMENT OR WHERE THE CLIP SNAPPING MAY PUT SOMEONE AT RISK (The clip atop in my opening photo is the original [PVC] which I took as a model)
