A mounting device for use in masonry and the like comprises an expandable member adapted to be received in a hole of a structure and an expander member adapted to expand at least a leading end of the expandable member. A shaft member is provided which has a first portion located in the hole and connected to the expander member, and a second portion outwardly projecting from the hole towards an object to be mounted and adapted to carry the latter at a distance from the structure. A first sleeve-shaped element encloses the first portion and a section of the second portion of the shaft member over a length corresponding to a part of the distance between the structure and the object. A second sleeve-shaped element encloses another section of the second portion of the shaft member over a length corresponding to the remainder of the distance. The second sleeve-shaped element is adapted to support the object to be mounted and is mounted on the first sleeve-shaped element for turning movement relative thereto. The mounting device may also comprise a ring-shaped member located between the expandable element and the shaft member and connected with a front end portion of the first sleeve-shaped element. |
