Locking banana plugs typically use a knob driven screw to wedge the solid split banana fingers very tightly against the inside of the 5-way binding post, so tightly, that they are very difficult to remove, hence the "locking" designation.WBT examples:

(third one down)In my opinion, the use of regular spring loaded banana plugs is too iffy in terms of making a good low resistance contact. Some of the so-called premium spring loaded banana plugs have a fair amount of spring tension, and more than 4 fingers, these are what I consider marginal, but the run-of-the-mill banana plugs with just 4 wimpy fingers that get loose after a few insertions and removals, those are worse than bare wire (which ain't so great either).
My recommendation: if you can't use spade lugs with either a properly crimped connection (ordinary pliers do not a proper crimp make!) or a well done solder joint, then the next best option is a locking banana plug, as long as it can be locked so tight, that you can not remove it with normal finger strength.
