Abstract
A device () for detachably connecting two abutting structural parts () comprises a tie member (), adapted to be at least partially inserted in a recess () formed in a first () of the structural parts (), and a locking element () operable to be disposed in a second () of the structural parts () and to cooperate with an engagement surface () of a rod member (), slidably housed in a body () of the tie member (), to pull the same towards the second structural part (). The body () is provided with a first, expandable, portion () adapted to frictionally engage the recess () and with an engaging zone () cooperating with an expander region () of the rod member () operable to expand the first, expandable, portion () of the body () upon displacement of the rod member () relative to the same. The rod member () is provided with a traction portion () radially outwardly extending therefrom and adapted to cooperate with abutment means () radially formed in the body () of the tie member () at a predetermined axial distance from the engaging zone () to effect a substantially simultaneous displacement towards the second structural part () of the first, expandable, portion () of the body () of the tie member () and of the first structural part () in frictional engagement therewith.
