Looking for a male and female PCB receptacles to mate with female and male plugs

I want to take a power cable and cut it in half. I then want to crimp a plug on each cut end and then be able to connect those two plugs together - in other words, there's a male plug on one cut end, a female plug on the other cut end, and the two can be connected to complete the circuit like it was before cutting the cable.

I am also building a relay board, and its purpose is to break/connect the power from the supply.  Most of the connectors I find feature one type of plug (i.e. male) and one type of receptacle female).  Instead, what I'm looking for are pcb-mounted male and female receptacles to match female/male plugs (respectively) that were crimped onto the cables.
  Does something like this exist?
The reason I am trying to pull this off is because I want to have the option to use the power cable as a stand-alone item without a "gender-changer" adapter, and I also want to key the connectors such that you can only plug the supply end of the cable into one receptacle on the PCB and the output end of the cable into another receptacle on the PCB. 
Ideally I'd like something that has a latch. We're talking low-voltage here, so something the size of a standard plastic computer Molex connector, but 2-pin. 
Thanks!

Molex make all sorts of connectors like this and it should be possible to find some that do what you want - I have some inline ones in my spares box  I think.  The requirement for both board mounted and inline types does complicate it, but it should still be possible.  a quick search on Farnell turned up thousands of connectors, and I don't have time now to wade through them or narrow the search, but I will try and do so later if I can.

Mike,It sounds like this is a "one-of" type of project. If it is then one way around the problem is to create your own "PCB mount" part by crimping solid wires into the contacts then inserting them onto the board. Unfortunately, this isn't a very mechanically stable mounting.
A better alternative is to get panel mount connectors of each type. Then you crimp short wires to the contacts and solder the other ends of the wires to the board. Then mount the connectors onto the box that you put your board in.

Mike - a bit more searching came up with this from TE Connectivity:https://www.te.com/usa-en/plp/rectangular-power/YG2dB.html?q=&n=503552&d=545388&type=products&samples=N&instock=N&q2=mate%20n%20lockThey have a range called Mate n Lock, and also a min version of same, you can probably find connectors for all your requirements among them.It might be worth while going to a manufacturer like TE or Molex and outlining your requirements (number of ways, current capability, specify locking connectors, board mount and inline cable, and see what they offer you.

You know in life when you have one of those "duh" moments where you wonder why you hadn't thought of that before?  Well, I just did with this whole connector thing...
I was looking at the connectors on the Molex site as David suggested, the mini fit jr to be specific, and sure enough, they do make a PCB-mounted female end that matches what would be on the plug end... except for the fact that it's 4 pins, not 2, and it wouldn't have a retaining clip.  Dang, I thought... that's a bummer.  But, then it dawned on me - why the heck am I trying to use two 2-pin connectors instead of one 4-pin connector?!  If I use a 4-pin connector, it's keyed and I won't have to worry about plugging the wrong connector in the wrong socket.  And while I can't plug each end of the cable into each other, I can make a little "jumper" plug that I can plug into that just completes the circuit and allows me to use the cable like normal.  It really simplifies my board layout, there are less connectors, and overall it's a cleaner setup.Essentially, I was so focused on what I was trying to accomplish that I think I was really overcomplicating it and turning something pretty simple into a one-off solution like Elizabeth was saying.
Thanks so much for your suggestions and guiding my way down the path to a solution!

Mike - nice thinking.  Sounds like you are on the way to sorting out your problem.BTW your above post came out twice.  Happens sometimes when it doesn't seem to post the first time, so you post again and it's there twice.
For a limited time you can edit and delete posts.  If you see three dots at the top right of your post, click it and you get options to edit or delete, in this case delete the second one.Cheers // David

Yeah, it was strange because I could tell it double posted (within 5 seconds of each other), but I'm a new user and under moderation so I couldn't delete it
