John coughed up some electrons that declared:

I have a property I rent out to tenants and some parts of some windows
have
"gone missing". They are pieces of uPVC approx 50mm long by 20mm wide and
6mm thick with tapered ends that the handle 'sticky out bits' rest on when
the windows are closed. Does anybody know the corresct term for these
bits and if they can be obtained from anywhere either high street or
t'internet?

Cheers

John

Along with the internet suppliers already mentioned, if you can retrieve one
from another window, a glazier in town should be able to sell you some, or
get them in.
