Abstract
A pipe connection arrangement for a water tank of a heat exchanger of a motor vehicle heater includes a pipe equipped with a collar at a pipe end for inserting into a connecting sleeve at the water tank. The pipe is provided with a seal on a first side of the collar, with the seal being pressed tightly into a recess in the connecting sleeve. A holding clamp rests on the other side of the collar facing away from the seal with the holding clamp being formed asd a U-shape. The clamp is developed in such a way that its U-bracket-shaped part rests tightly against the pipe exterior. This design results in the load transmission being evenly transmitted over a relatively large surface area. The sleeve includes openings formed as slots for receiving the clamp, with a reinforcing web provided in the center of the slots. The clamp is secured by another gripping part that projects from the bracket part and engages behind a reinforcing web of the connecting sleeve. Another advantage the invention provides is the possibility of mounting pipes closely at water tanks without any screwed connection and providing a largely even sealing force.
