A quick-connect coupling is disclosed for thin-walled pipes which can accommodate pipes of the same internal diameter but of differing wall thickness, the coupling member being constructed to deform pipes of less than maximum wall thickness into a substantially elliptical condition in which the coupling is fully seated, bolting pads of the coupling being spaced from each other to induce deformation and seating of the pipes upon tightening of the coupling.

A quick-connect coupling for thin-walled pipes of resiliently deformable cross-section, said coupling comprising: plural arcuate coupling members each having a radial internal groove for the reception of an elastomeric gasket; a radially outwardly extending pad at each circumferential end of each said coupling member, each said radially extending pad being adapted to receive securing means for securing said coupling members to each other in clamping engagement with said pipes; each said radially extending pad having an end face which, in the assembled condition of the coupling, is spaced from and extends substantially parallel to a plane which includes the central longitudinal axis of said coupling member and which lies beyond the associated end of said coupling member; and, internal grooves at each axial end of said coupling members for the reception of arcuate projections on the outer periphery of the respective pipes.
