Abstract
A member for fixing by radial expansion, the member comprising a pull rod having an expandable plug mounted thereon and surrounded over its entire length by a split ring, one end of the pull rod being connected to an endpiece, said plug being sandwiched between said endpiece and a thrust part also mounted on said pull rod, the member further including means enabling said endpiece to be moved towards said thrust part in such a manner as to compress the plug axially, thereby causing both it and said split ring to expand radially, wherein when said plug is uncompressed and at rest, said split ring is longer than said plug, said thrust part including a portion that constitutes a ram suitable for penetrating into said split ring, and wherein the end of said split ring includes a radially inwardly extending collar having the expandable plug and said endpiece bearing against opposite sides thereof.
