Claim 1
Independent Claim
177 words
A retaining disc for cavity wall insulation, comprising a substantially disc-shaped plastics plate provided with a central opening forming a seat for a cavity wall tie, and communicating with a slot extending up to the outer rim of the disc through which the wall tie can be moved towards the seat when pressing the disc on a tie, which central opening is surrounded by a lug forming part of the disc and stiffening the latter but being elastically deformable, said lug being interrupted at the slot, characterised in that the lug (5) is in the form of a ring coaxially surrounding the seat at some distance, and in that, substantially aligned with the rims (4) bordering the slot (3), two flexible strips (7) each extend mutually parallel from a respective extremity of the interrupted lug (5) towards an opposite point thereof, which strips (7) are integral with this lug (5), said strips (7) each being provided with at least one recess (8), the recesses (8) of a pair opposing one another and forming together a tie seat.
