Claim:
Mounting assembly for use in the assembling of items, comprising a rivet bush with a first end having a deformable zone for introduction through coinciding holes in the items and a second end having an external thread on which a cooperating nut is provided, and a draw-rod housed in the rivet bush, a first end of the draw-rod having a draw-head housed in the deformable zone, the draw-head having a larger diameter than the draw-rod and a break zone being formed between the draw-rod and the draw-head, and a second end of the draw-bar extending out of the second end of the rivet bush, drawing on the second end of the draw-rod being adapted to cause collapsing of the deformable zone, for fixing the rivet bush in the items being assembled, until a break occurs in the break zone, wherein the second end of the rivet bush has a non-cylindrical internal cross-section for receiving a tool for enabling dismounting of the nut after the draw-rod has been broken and the deformable zone collapsed, and wherein, in a dismounted state of the rivet bush, the break zone lies in the first end of the rivet bush.
