should banana clips be snug or not?

[Simp-Dawg]

on my speakers (b&w dm610i's) the banana clips i have my speaker wire terminated in just kind of sit in there, it's not a snug fit.  should i be concerned or is that normal?

With my Klipsch KLF10s. the bananas fit nicely but are not tight - that is, they can spin but they are in there. Contact seems to be good - sounds fine...
