The appliance comprises a securing device 1 with a shaft 2 which extends through an insulation layer and with its front end section 3 is anchored in the building wall, and at least one mesh attachment 30 with a shaft 32 which has locking members 33, 34 for engaging with the securing device 1 and mesh-holding members 31, the securing device being provided with a hole 9 for mounting the said mesh attachment. According to the invention, the hole 9 of the securing device 1 is formed with at least one outer radial recess 15, 16 for insertion of the locking members 33, 34 of the mesh attachment, which recess extends axially from an outer end surface 10 to an inner catch surface 14 facing away from the latter. The mesh attachment 30 is brought into locking engagement with the securing device 1 by turning about its centre axis, the locking member 33, 34 being brought into position behind the said inner catch surface 14. The said axial extent of the recess 15, 16 is smaller than the distance between the locking member 33, 34 of the mesh attachment 30 and its mesh-holding member 31. <IMAGE> |
