The invention relates to a perforation connector with deformable anchoring piece which is a development of the perforation connector with mechanical fixing for perforation holes of so-called rectangular shape as disclosed in FR 0407037. The connector comprises a deformable anchoring piece (2) and a cradling and connecting piece (4). The deformable anchoring piece (2) is provided with two anchoring and clamping elements (5) on the medial generatrix thereof and two sealing joints and a central opening. Said anchoring piece which is sufficiently flexible that the radius of curvature thereof may be altered on tightening against the inside wall of the collector (1) within which said piece may be placed through the rectangular opening (3), previously made in the wall of the collector, said piece being in the form of a part of a cylinder the initial external diameter of which, that is to say before deformation, is substantially greater than the internal diameter of the collector. After anchoring the cradling and connecting piece to the deformable anchoring piece, then clamping said cradling piece against the external wall of the collector (1), the peripheral joint (9) of the deformed anchoring piece guarantees a prefect seal with the internal wall of the collector thanks to the presence of the single anchoring and clamping elements (5) and the associated devices (nuts, screws, pins or other devices).
