Abstract
A housing having a socket surrounded by an annular flange is connected to a tube having a raised annular shoulder. The tube is inserted in the socket, and then the flange is deformed radially inwardly to capture the shoulder in the housing. The flange is also recurved alongside the sidewall of the tube on a side of the shoulder opposite the housing to support the tube against bending. The flange includes an inwardly directed wall having an array of raised features positioned to enhance frictional engagement between the wall and the tube when the raised features are forced against the tube as the flange is deformed. In this way rotation of the tube in the housing is inhibited.
