That looks like them. I still have some of the Monster bananas (brag, brag) kicking around, but they were pretty well discounted when I bought them. I think the last big package (brag) of terminations I got were Sewell, though they were the locking bananas. I splurged at one point and had the ultrasonically welded speaker cables from Blue Jeans Cable for my main left and right channels, but when I moved my system to the basement, I ran the cables a different way and needed to self-terminate (ow). None of the differences in cables and connectors ever resulted in an appreciable difference in sound quality, of course. I stick with bananas for the convenience.
As far as locking versus normal banana connectors, I never had a problem with the normal ones slipping out, so for most people I imagine it's going to be a non-issue.
