ABSTRACT:
The fixing device comprises a body adapted to be secured directly onto a brittle wall or secured to the brittle wall with a member to be attached to the wall interposed therebetween. The body is formed with at least two guide holes passing therethrough from the top to the bottom thereof each for receiving therein a fixing member such as a set screw or a nail so that it is driven into the wall to thereby fixedly secure the body onto the wall. The guide holes are oriented in such an inclinded direction with respect to the normal to the wall that the fixing members do not intersect with each other and do not extend in parallel to each other when they are inserted into the body and driven into the wall, thereby permitting the body to be securely fixed to the wall. An engaging member having integrally formed therewith a supportng portion such as a hook or a hanger may be detachably engaged over the body. Alternatively, the body itself may be integrally formed with a supporting portion such as a hook, a hanger and a ring.
