Where can I get a replacement nylon chain connector for Cardale DC650N?

I'm new to this forum, but hoping someone can help me source a replacement nylon chain connector for my Cardale door.  I'm not sure of the proper name for the part - it doesn't appear in the DC650N manual, but I've used every search term I can think of on Google, without success.  

The part concerned is a 2-part white nylon thing, about 140mm long (see photo).  The two halves clamp together like a razor shell around both ends of the motor chain and are held together with integral side clips plus 4 screws along the central axis, effectively completing the chain. Mine snapped when the closing overhead door caught the roofbars on my car....   One half of the connector bears the number 8007133 and the other 8007014.

Not sure how relevant, but the door is a Cardale Vertical S/A Futura (AVSR 1470 – 4128 x 2000) up and over type, installed c 2001, fitted with a DC650N motorised operator.

If anyone can point me in the right direction, I shall be very grateful

Thanks in anticipation

I'm not familiar with the DC650N operator I'm in the U.S. and it is a European operator but I do know that it is/was manufactured by Marantec. You should contact Marantec to find the part you are looking for.

Many thanks GDZone

I have established that the part I need is an “E” King (Marantec) Chain Bullet.  Marantec are trying find one for me.  Thanks again for your assistance on this.
