Abstract
A heat exchanger (1) has a plurality of fluid flow tubes (5) secured adjacent their ends by tube sheets (6, 7). Cleaning elements (18) are adapted to shuttle back and forth in the tubes and are adapted to be captured by elongated slotted baskets (17). A removable cleaning element retainer (28) is adapted to be snap fit into the end of each basket via flexible clip legs (30) terminating in radially outwardly extending prongs (31). A notch (39) formed in the outer slot end receives a retainer prong and thereby holds the retainer against basket-wearing rotation.
