The CPSC publishes the consumer product recalls it issues in the United States, and searching that database for resistance bands, cords and tubes returns eight records going back to 2011. Read them and they sort almost entirely one way. Two are the band pulling out of its handle, on an SPRI set in 2019 and a HomeProGym set in 2026. Two are a plastic clip in the load path breaking: on an Ethos pull-up assist in 2019, where the clip sat on a nylon web band carabinered to the band, and on Fitness Gear tubes in 2011, where it joined the tube to the handle. Two are the plastic ball on a door anchor letting go, on Bollinger bands in 2014 and Target Embark cords in 2011. One is a band coming out of its cloth loop, on Perfect Fitness bands in 2013. The eighth, Fitness Gear tubes in 2017, is the only one where the rubber itself broke.
That is why this page ranks on the joint before anything else. A flat band, a plain loop or a mini loop has nothing bolted to it and cannot fail the way seven of those eight did. A tube with handles and a door anchor can, which does not make it a bad buy: it makes the maker who explains how that hardware is built worth more than the one who does not mention it. Consumer Reports arrives at the same split from the other direction, publishing no single ranked list for the category and dividing its coverage into tube bands with clips, tube bands with handles, mini loops in elastic, mini loops in cloth, flat bands and power loops. The attachment is the category boundary, not an angle we invented.
