A modular connector, to be assembled with other such connectors into a switching frame designed to interlink incoming and outgoing lines of a telecommunication system, comprises a flat prismatic housing of generally rectangular outline with a bank of input terminals and a bank of output terminals fitted into a pair of recesses on its opposite longitudinal edges. Leads extending from the two terminal banks within the housing are bent to emerge at a major housing surface overlain by a printed-circuit board whose conductor strips connect them with two further sets of leads emerging from the same major surface adjacent one of its transverse edges, the leads of these letter sets extending into a junction box attached to the housing along that transverse edge. Within the junction box, normally closed by a hinged door, contacts tied to the two sets of leads can be selectively interconnected or, if desired, extended to testing equipment.
