Reduced Dobbies 10p sale items - rainwater diverters

Reduced to 10p from £15 and £4.50, but I haven't got a clue what they are, maybe this will help somebody who knows, I'll amend the post title if anybody tells me what they are (edited after link provided by A-A):

Appear to be both rainwater diverters reduced to 10p each, one for round pipes and the other for square pipes, possibly both reduced from around £15 each. They were in Fenny Stratford Dobbies.
