This is one of the shortcomings of Amazon; you sometimes get new (old stock) aka "NOS." In checking on the Blue Ox website, they no longer show the old version with metal fittings. And, yes; theIr price is higher, but you know what you'll get.
In checking on Amazon, the one
@Neal linked to is sold by "Amazon.com." That means it comes from stock in the Amazon warehouse. Since the Blue Ox P/N is the same for the old and new versions (BX 88206), that warehouse stock probably includes both old and new versions. The warehouse people don't know the difference; they just go by PN.
I checked several of the 30 other alternate sellers listed on Amazon with that item and it appears that many...possibly all...of them are showing the old style. My guess is that Blue Ox closed out the old version to a close-out buyer that offered them to resellers at a lesser price.
So, to be guaranteed of getting a new style BX88206 cord, buying from Blue Ox is the safe bet. Otherwise, keep returning and re-ordering until the right version shows up. That would be a PITA, so if it was me, I would order directly from Blue Ox to be sure of getting the one you want.
Too bad that manufacturers/suppliers don't change their PN when a new version comes out. Just adding "-B" or "-2" would solve the problem.
