You have multiple choices, including Connecting Links (2 ''halves'' of a link that are joined by peening rivets) and Mid Links. The former are galvanized, drop forged and claim to have a strength comparable to the proof coil chain itself (which is what I assume you have). Personally, I''ve always been shy of these as I wonder if the peening will remain sufficient should the rode work on a coral head or rock while surge racks the anchorage...but that''s just me being anxious.
Mid Links are IMO far superior: absolute security with solid clevis pins and strong enough to join high tensile chain of the same size without creating a weak spot. They won''t slip right thru your gypsey unnoticed but my S/L manual never spits one out and I''ve been using one for the last year in the Caribbean. Their one failing is that, despite how WM titled the page where they are prominently listed (p. 689, 2002 Cat.) they are not galvanized. Periodic spraying with e.g. Boeshield will keep them at full strength but they will surface rust over time. Given their strength (twice the WWL rating) and security, I think the boat''s rode is due a new one each year or two.
The other choices are pricey, I''ve seen several of them fail, they are larger & more cumbersome and/or they offer poor working load limits.
