There is a type of shackle suitable for jibsheets but they are pricey

18" of line, a little whipping, and you're done.

Who needs a shackle?

Racing boats that do frequent jib changes, often in the dark. Shackles
are quicker and more reliable in those circumatances. The racing
shackles are also very sleek and low profile which minimizes the
chances of the clew hanging up on the shrouds during a tack.
