It shows up under the consumers in queue details.

Yes, it shows up there. I just forcefully closed one of the:
[[
# rabbitmqctl list_channels name connection | grep 44478
client:44478 -> server:5672 (1) <rabbit at rabbitmq02.2.10377.40>
# rabbitmqctl close_connection "<rabbit at rabbitmq02.2.10377.40>" "close
hanging connection"
Closing connection "<rabbit at rabbitmq02.2.10377.40>" ...
...done.
]]

This cleared that connection. The really weird thing is that lsof only
shows that connection on the server, not on the client. I.e. I could find
this on the server:
[[
beam.smp 29152    rabbitmq   19u  IPv6 523865701      0t0  TCP
server:5672->client:44478 (ESTABLISHED)
]]
but not on the client side. That it's IPv6 confuses me "a little".

I'll send that off list.

Also, do these items ever go away?

I can't say for sure, as I haven't checked to see if some of them go away,
and new ones "replace" them, but the number of hanging connections doesn't
ever seem to go down, no.

No.
