You're not likely to find a commonly available connector that will be as compact as just soldering the ends in a lap joint (wires meet end-to-end) covered with shrink tubing. The bundle can then be secured to the housing or other stationary part to eliminate any significant motion from vibration.
The actual tubular contacts in those Euro-type terminal strips can be removed from the nylon blocks (after taking the screws out), then the bare tubular connector/terminal is a plated machined brass connector with 2 screws for inserting wire ends into.. but then there is the bulk of the connectors and screws.
A small circuit board with two rows of holes can be used to thread the wires up thru 2 adjacent holes, lay them flat against each other (and the board) and solder the lap joint. The small board, even perf board acts as strain relief and secures the joints, which can be covered/coated with corona dope or liquid tape.
Most miniature terminal blocks are usually intended to be used as a solderless user interface (inputs-outputs etc), and are generally part of a circuit board or structural component of an enclosure. Loose/free hanging cord-end or bulkhead pass-thru types aren't as common.. that's where actual connector ends come into play.
