Italian to English Tech/Engineering Mechanics / Mech Engineering digital printing

This is an item -- **attacchi elettrici e pneumatici*** -- in a list, under the heading of "Technical Details" describing tilting and transport tables for a digital printing line.

There are several options: I found lots of hits for "pneumatic couplings", as well as "pneumatic fittings" and connectors.
"Electrical couplings and fittings", on the other hand, brought up lots of entries about conduit fittings and cable and conduit connectors. Clearly, conduit isn't part of the original Italian text.

I know I haven't given you much to go on, but does anyone know what the appropriate term, that would apply to both electrical and pneumatic, might be in this case?
Thanks in advance.
