Insulating-material retaining means with an expansible dowel shank

摘要

The invention proposes an insulating-material retaining means with an expansible dowel shank (1) and a retaining plate (2), on the dowel shank (1) of which fins (11) project radially beneath the retaining plate (2). The fins (11) engage into an insulating-material panel (4) which is to be fastened and prevent the insulating-material retaining means from co-rotating when a fastening screw (3) is screwed in. <IMAGE>
