Blinds/fly screens 2010 broadway

One of my fly screens has dropped, no tension, the small slotted block that holds the tongue at the end of the shaft is broken.
I cannot identify the brand. Have looked at spare parts sites and cannot find the part.
Any help please

We had the same thing happen recently to the blind of the big overcab skylight on our Broadway. As it is still in warranty the repair was done by AS at a recent hab check. It might be worth contacting them to find more details. It was done within 2 hours so they presumably hold the relevant part in stock.

Good morning. I have solved the problem. the blind is Remis, part is Retaining Clip SP1044, obtained from leisureshop direct Their ref is 239237.  2 off £7.03 inc postage. Looks like it had been butchered dont know by who but the supplying dealer has used a similar technique on other "repairs prior to purchase"
