A modular contact arrangement for connecting various protective and/or monitoring devices to phase lines 6, 7 of a cable head in a telephone distributor frame includes a plurality of spaced, springy contact blade pairs 5a, 5b, themselves arranged in associated pairs 51-52, 53-54, with a common ground bar 60 having individual springy fingers or blades 61, 62 interleaved between each associated pair in a comb-like manner. A circuit card 4 having three parallel conductive strips 41, 42, 43 printed on at least one face is configured to be insertable between two associated pairs of contact blades in a tongue-like manner such that electrical connections are established with such blades and with an interposed ground blade. Various circuit devices may be mounted on or connected to the card.
