Yes they do need a proper connector, those anti-short bushing do not comply, unless you were in the Phoenix area they have a local amendment allowing that type of install.

They may have the same here, everyone I see is like this

Just because "everyone does it" ... I would not want to presume that it is approved or acceptable - I would write it up and let an electrical contractor provide written documentation from the local AHJ that they are okay with it and approve of that installation.

That is what I did. Thanks

These clamps work fine in this application. You can get them up to 1 1/2" and can be installed without removing the wire.
