French as suggested previously or French style? As far as French goes, the slot in the French ones is proportionally longer and the hole is flat rather than round. In France they are often referred to as "T" sockets. These certainly aren't modern French phone sockets. Just look at the picture above. French phone plugs are enormous and you wouldn't be able to plug two in side by side in one of those unknown sockets

As for "French style", apart from a vague similarity in the shape of the hole I don't see anything else in common. A French socket only has one hole. These sockets all have two holes in strange orientations. Why would you do that rather than have two or three sockets in the same orientation like a German TAE socket? The holes look to me as if the pair are related and whatever plug goes into them is plugged into both at the same time.

Maybe it's worth pointing out that although TAE sockets may appear to be double or triple, the sockets are actually different, being either F for telephones (Fernmeldegerät) or N for non-telephones (Nicht-Fernmeldegerät). N sockets are for devices with an input and an output whereas F sockets are for devices which terminate the line. The idea was you could plug something like an answering machine into the N socket but the line was routed further (either within the socket or the answering machine if one was plugged in) to a phone plugged into the F socket. A triple socket is NNF for say a modem, answering machine and phone. You couldn't put a F plug into an N socket or vice versa.
