Below, is a connector as provided on a 3D printer tool head (Hot End). This is a standard design used on all of this organizations tool heads.
As you have probably already guessed, I have damaged one of my connectors removing the connector.
Design 101 - don't ever do this in a field service-able connector ever folks.
