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.

A quick connection union for a pipe with an end flange, comprising a union body, and a quick connection device for connecting said union body to the end flange of said pipe, said device comprising an annualr supporting structure having thereon a plurality of movable connecting elements disposed to thrust and lock said end flange against said union body, and characterized in that said supporting structure is releasably engaged in a self-centering manner with a substantially segmental-spherical reaction surface formed on the union body coaxially thereof, and characterized in that said connecting elements consist of a plurality of locking segments slidably engaged with axially movable control bars through cooperating, parallel teeth formed on confronting surfaces of said segments and said control bars, respectively, said teeth being inclined obliquely to the axis of said union body and being operative to convert the axial movement of said bars into a corresponding oblique, radial translational movement of said locking segments.
