Abstract
A heat exchanger has a casing formed with two adjacent apertures to which two tubular pipe connections are secured. The apertures in the casing are so configured as to act as one half of a bayonet fitting, the other half of each bayonet fitting being a bayonet end portion fixed to each pipe connection. These bayonet end portions are adapted to be put into a locking position on the apertures, and are provided with base portions which are configured according to the spacing between the two apertures. The base portions have stop means which are arranged to cooperate with each other to lock the end portions in position when both of the latter are in their locking position. The invention is especially applicable to motor vehicle engine oil coolers.
