Abstract
A motor vehicle heating device with an exhaust connection piece (3) and a baffle plate (9) located near its exit opening. The baffle plate (9) is attached to the exhaust connection piece (3) by means of a spring element (7), preferably by means of hook-shaped end (10) of the spring which fits into recess (6) of a flow-dividing bulkhead (5) of the exhaust connection piece (3). Another part of spring element (7) is made as a compression spring which has compressible outer part (11) which rests against a shoulder (12) of the exhaust connection piece (3). The invention enables simple, cost-favorable attachment of a baffle plate on an exhaust connection piece by means of which outstanding noise damping is achieved.
