ABSTRACT:
An improved system for attaching a connecting device to the end of a spirally wound corrugated pipe section is disclosed. A conventional connector element is used which includes a first cylindrical portion adapted to connect to a corresponding connector element and a second cylindrical portion adapted to be inserted into the end of the corrugated pipe section. The outer diameter of the second cylindrical portion is approximately equal to but no greater than the inside diameter of the corrugated pipe section. A collar having a cylindrical portion with an inwardly directed circumferential flange is fitted over the end of the pipe so that the flange is beyond the end of the pipe section. The cylindrical portion of the collar has an inner diameter approximately equal to but no less than the outer diameter of the corrugated pipe section. The cylindrical portion of the connector element inside the end of the pipe section is forced radially outwardly to crush the end of the corrugated pipe segment flat against the collar. An axial portion of the overlapping connector element, pipe section and collar in combination is distended outwardly to form a bead. Crushing the end of the pipe segment between the connector element and collar and formation of the bead provide an air tight connection between the pipe section and the connector element.
