As Elaine mentioned the C-alpha atoms are connected by a chain trace.  Another way to hide that is if you click on the ">" to the left of your model the Models panel it will show submodels and one will be named "chain trace" and you can click the hide checkbutton next to that (under the eye icon).

Hello,
 
I am trying to show only sidechains in one model, so I can compare rotamers with another model where I am displaying cartoon and sidechains. However, when I display sidechains using the sidechain selector (e.g. “show #1 & sidechain”) the CA atoms become linked by tethers.

How can I suppress this display? I can see its possible to suppress tethers between cartoon helices and a sidechain in the same model but that doesn’t seem to apply here as I’m not showing the cartoon at all in the models where the CA tethers are present.
 
KR,
