An electrical connector block comprising plug and/or socket units mechanically coupled together side by side. Each unit has an insulating housing of rectangular cross section. One pair of opposite sides has a dovetail tongue and groove perpendicular to the plugging direction, and the other pair has a dovetail tongue and groove parallel to the said direction. This construction prevents coupled units from being pulled apart when plug and socket blocks are plugged or unplugged.

An electrical connector unit adapted to be assembled with at least one further such unit to form a multi-pole electrical plug-and-socket connector block, which unit comprises (a) an insulating housing; and (b) electrical contact means in said housing defining a predetermined direction of making a plug-and-socket connection; (c) said housing having a coupling region for mechanically coupling said housing to adjacent units, said housing having at least in said coupling region a rectangular cross section transverse to said predetermined direction, whereby said region has a first pair of opposite external faces and a second pair of opposite external faces, said first pair consisting of a first face provided with a first coupling groove having its longitudinal axis extending in said predetermined direction and a second face provided with a first coupling tongue having its longitudinal axis extending in said predetermined direction and adapted to couple with a said first coupling groove of an adjacent unit by relative sliding movement of said units parallel to said predetermined direction, and said second pair of faces consisting of a third face provided with a second coupling groove having its longitudinal axis extending transversely to said predetermined direction and a fourth face provided with a second coupling tongue having its longitudinal axis extending transversely to said predetermined direction and adapted to couple with a said second coupling groove of an adjacent unit by relative sliding movement of said units transversely to said predetermined direction parallel to said third and fourth faces thereof.
