<p>A quick connection device has a supporting structure for connection elements constrained to the union body by means of radial engagement members engaged in a movable manner with a substantially spherical reaction surface of the union body. In this manner any coplanarity defect or difference in thickness of the end flange of the pipe to be connected is compensated for through appropriate rotation of the supporting structure of the quick connection device along said spherical surface.</p> |
