<p>The fixing dowel has a sleeve shaped body (6) with a screw (8), where a fixing section (10) is attached to the body, which is fixed in a bore of the wall by the fixing section. The sleeve shaped body has two sections (12,14), sequentially arranged by another section (18). The later section is rigid with an enlarged radial diameter. Third section slots (22) are formed in the third section by a spreading arm (38). The slots stretch towards the bore end of the body, so that the body is extended within the third section through a pressure force, which acts on the section while pulling the screw.</p> |
