A device ( 1 ) for detachably connecting two abutting structural parts ( 2, 3 ) comprises a tie member ( 4 ), adapted to be at least partially inserted in a recess ( 5 ) formed in a first ( 2 ) of the structural parts ( 2, 3 ), and a locking element ( 6 ) operable to be disposed in a second ( 3 ) of the structural parts ( 2, 3 ) and to cooperate with an engagement surface ( 14, 45 ) of a rod member ( 10 ), slidably housed in a body ( 8 ) of the tie member ( 4 ), to pull the same towards the second structural part ( 3 ). The body ( 8 ) is provided with a first, expandable, portion ( 9 ) adapted to frictionally engage the recess ( 5 ) and with an engaging zone ( 13 ) cooperating with an expander region ( 12 ) of the rod member ( 10 ) operable to expand the first, expandable, portion ( 9 ) of the body ( 8 ) upon displacement of the rod member ( 10 ) relative to the same. The rod member ( 10 ) is provided with a traction portion ( 15 ) radially outwardly extending therefrom and adapted to cooperate with abutment means ( 16 ) radially formed in the body ( 8 ) of the tie member ( 4 ) at a predetermined axial distance from the engaging zone ( 13 ) to effect a substantially simultaneous displacement towards the second structural part ( 3 ) of the first, expandable, portion ( 9 ) of the body ( 8 ) of the tie member ( 4 ) and of the first structural part ( 2 ) in frictional engagement therewith. |
