<p>A heat exchanger includes a heat exchanger body (10) from which a connection duct (12) extends. The connection duct (12) includes and elastically deformable free end and two engaging walls (20) formed in respective rectangular apertures (18) proximate the free end of the duct (12). A coupling tube (14) for coupling the heat exchanger body (10) to a hose of an expansion tank includes a first portion (30) receivable in the connection duct (12) which includes two tangs (34) engageable with the engaging walls (20) to secure the coupling tube (14) within the connection duct (12), and a second portion (40) connectable to the expansion tank hose. A U-shaped recess (22) at the free end of the connection tube (12) engages a U-shaped locating portion (50) of the coupling tube (14) to align the coupling tube relative to the heat exchanger body (10). <IMAGE></p> |
