Strange crimp connector for BT phone power

[TheJay]

I have an adapter which plugs into the mains and on the other end has what looks like an RJ11 crimp connector, but the clip is oriented to the left rather than the middle.

I want to shorten the cable as it is far too long and had anticipated simply cutting the appropriate amount of the lead and putting a new RJ11 crimp connector on the end. However, a standard one does not fit!

Can someone please tell me what the correct crimp connector is called, where I can get new ones and which crimping tool will work?

The crimp connector I am referring to is on the left of this image.

Thanks for your help.

I need to let you all know that the crimpers actually work great, there is a small piece of metal held in with a screw over the DEC crimper for some reason (no idea why).

If you unscrew and then remove the piece of metal it crimps DEC connectors perfectly!

That piece of metal can be turned around for different crimps to allow the connector to sit correctly in the tool.
