i got stuck once at a conference because I forgot my cones for my pump, so i set out to create an "emergency" stock of cones for the pump and car. I bought these connectors. I know there is a picture...maybe i didn't see it...maybe it wasn't there...maybe i am not that famililar with pump products...but I was SOOOO disappointed to find that these did not come with the yellow half circle things that make these connectors work with the shields. ugg.... then, i was at babies r us and those yellow things cost as much as a fully assembled cone, so i just bought the fully assembled cones... i am disappionted this didn't come more complete for the price....
