Not a multiport connector that individually secures each conductor - like a WAGO, Polaris connector, terminal strips, ground bar....
As you can see the center conductor (white 4th from the left) is relatively straight compared to the conductors that were next to it and the outer conductor. Even though the center white is not twisted with the other ones, with the pressure of the wire nut and the wall pressure of the other conductors I could not pull the center one out. So it is in there for good.
