It fits but I still don't know if I should try it, I've found the following in the S-VIDEO Wiki.
The 4-pin mini-DIN connectors seem to be common on TVs, VCRs, and DVD players. The 7-pin quasi-DIN connectors seem to be more common on computers. The 7-pin socket accepts the 4-pin plug and the S-video signals are available on the matching pins. When a 7-pin plug is inserted, one of the extra pins carries a CVBS composite video signal for non S-video displays. Some graphics cards require the remaining two pins to be shorted together to enable the CVBS mode. Many newer cards (especially those with inputs and outputs) will also require the 7+ pin connector and will not just take the s-video cable directly. If you try to connect it, you will damage the cable and/or the card.
It would be great if someone could confirm the method who had already try it successfully.
UPDATE --> It works <-- UPDATE
