96), said fitting (62; 86) further comprises: at least a third surface located on said first housing portion (12; 88); and at least a fourth surface located on said second housing portion (14; 90); said third and fourth surfaces being in a facing relation; said third surface is located on one of said lugs (70; 112) positioned between two of said receptacles (16, 18; 92, 94, 96); said fourth surface is located on one of said lugs (70; 112) positioned between said two receptacles (16, 18; 92, 94, 96), and said third and fourth surfaces are not angularly oriented. first and second housing portions (12, 14; 88, 90) attached to one another and defining at least first and second receptacles (16, 18; 92, 94, 96) said first and second receptacles respectively defining first and second openings (20, 22; 98, 100, 102) for receiving said pipe elements (24, 26; 104, 106, 108) said housing portions further defining a fluid path extending between said first and second receptacles (16, 18; 92, 94, 96); a plurality of adjustable fasteners (34, 116) attaching said first and second housing portions to one another, said fasteners (34; 116) being adjustably tightenable so as to draw said housing portions toward one another and bring said receptacles into engagement with said pipe elements so as to affix said pipe elements together; at least a first angularly oriented surface (76; 146) located on said first housing portion (12; 88); at least a second angularly oriented surface (74; 144) located on said second housing portion (14; 90), said first and second angularly oriented surfaces (76, 74; 146, 144) being in facing relation and sliding over one another when said fasteners (34; 116) are tightened to bring said first and second angularly oriented surfaces in contact, sliding motion between said first and second angularly oriented surfaces causing said first and second housing portions (12, 14; 88, 90) to rotate in opposite directions relatively to one another, wherein a plurality of lugs (70; 112) are provided extending from each of said first and second housing portions (12, 14; 88, 90) each of said lugs 70; 112) defining a hole (72; 114) for receiving one of said fasteners (34; 116); said first angularly oriented surface (76; 146) is located on one of said lugs (70c, 70d; 112c, 112d) on said first housing portion;
