Estimating the term…
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.
A housing for a heat comprising a casing defining two through apertures adjacent to each other and two tubular pipe connections, the pipe connections and the casing together defining securing means for securing the pipe connections on the casing, wherein each said pipe connection comprises a bayonet end portion for engagement in a respective said aperture, each of the said apertures being configured for bayonet type cooperation with the corresponding bayonet end portion so as to constitute with the latter the fastening means, each bayonet end portion comprising a base portion configured according to the spacing between the said apertures in the casing and defining stop means, the bayonet end portions being adapted to be put into a locking position in relation to the apertures, such that the stop means of the two base portions cooperate with each other when both bayonet end portions are in the locking position.
