A fastening plug consists of a sleeve and a plug insertable therein, which forces flaps of the sleeve out into engagement with the walls of a hole in a wall or similar. The sleeve is lengthwise open and formed from a piece of sheet, rolled together. It has flaps for engagement with the plug, by means of which the latter is locked against the sleeve such that drawing out and rotating is rendered impossible. <IMAGE> |
