ABSTRACT:
A fixing device for securing a sheet member to a substrate, having a stud projecting upwardly therefrom, comprises a cap member which is disposed over the stud and has inwardly projecting detents for engaging threaded portions of the stud. The sheet member has an aperture defined therethrough and within which the stud and cap member assembly project. A first clip member has a first flange portion for engaging one surface of the sheet member, and a body portion extending within the aperture of the sheet member so as to surround the cap member. A second clip member has a second flange portion for engaging a second surface of the sheet member, and a body portion which is also inserted within the aperture of the sheet member so as to be interposed between the cap member and the body portion of the first clip member. The cap member is provided with an annular groove, the second clip member is provided with an annular projection for engaging the annular groove of the cap member, and detents of the second clip member engage the body portion of the first clip member so as to permit engagement of the first and second clip members. The first and second clip members are also connected together by a flexible strap.
