Where can I find this or similar connectors

Oh yes, the Asians use those by the boatload. I never did identify the brand. The plastic's really soft isn't it. It may be a clone of a JST type.

They are soft enough that they would probably bend before braking. Just cannot seem to find something similar that I can put in-line.

Digikey, Mouser, etc..

Yes and Digikey has THOUSANDS of connectors. I have been unable to find similar connectors. I have spent hours trying to search through the digikey catalog but other then a few search terms which do not narrow it down to any reasonable number of items. Digikey is damn hard to find something like this if I do not have a part number.

True. However, if all you have is a photo, it's much easier to use the printed Digikey and Mouser catalogs to find something similar, than to browse the web catalogs. I can help if you don't have one.

However, I need to know the pin spacing in mm or decimal inches. Please don't guess as there are several spacings that are close, but not the same. Also, if the matching receptacle has round or square pins and if possible, their diameter.

Incidentally, few of the jacks seem to have manufacturers logos and names. However, the matching PCB receptacles usually have something marked on them. You may need a microscope to see it, but check the largest flat area.

Also, please note that this is sci.electronics.repair, which deals with repairing equipment. If this connector came from something repairable, supplying the maker and model number might yield the connector specs or vendor from the service manual. Otherwise, if you are building something using this connector, you might get better results in the various design, do-it-thyself, or hobbyist newsgroups and forums.
