Ill post this, just so you know what to look for.
Many places sell them...they vary greatly....thickness, , length, shape and size of swivel...no swivel ect ect
my advice to you is....look up every commercial fishing supply house you can find.... look for a clip 6" long if you can find it...make sure it has a swivel on the end....one that is big enough to tie your dropper( line to decoy) to. and buy the THINNEST wire you can find in 6 "
these things are made to help commercial fishermen feed out 2 miles of 1/4" dia line with thousands of hooks to catch tuna and bill fish and drag them along for days until they decide to pull the line it......
you don't need to pull a 1,000 lb marline around....... so the thinner ss wire clips are the ones you want...but you want them LONG so you can squeeze them with your gloves on!.... and do it fast!
if.... IF you look around , you might be able to find them in bags of 50 or 100 for 50 cents a piece.
