Abstract:
1. An internal combustion engine's cooling system comprising a coolant circuit, further a first sub-assembly configured in said circuit and fitted with a first pipe segment and a second sub-assembly in said circuit fitted with at least one second pipe segment, further a sealed connection between the pipe segments, either the first or the second sub-assembly being fitted with means for solidly joining it to an engine, characterized in that the pipe segments of the two sub-assemblies can be plugged into one another and are displaceable relative to each other, a seal being configured between the pipe segments, a resilient locking tang running parallel to the axis of the pipe segment of the second sub-assembly that is integral with said second sub-assembly and is fitted at its free end with a detent element pointing toward the second pipe segment, an elongated guide portion running parallel to and spaced from the locking tang between the second pipe segment and the locking tang is integral with the second sub-assembly, the first pipe segment having a pair of spaced-apart arms running parallel to each other and parallel to the axis of the first pipe segment wherein the spaced apart arms extend a length beyond the end of this first pipe segment and are integral with the first sub-assembly, the first pipe segment further comprising an axially parallel web positioned between the arms and configured to engage the guide portion of the second sub assembly and is fitted at its end facing the second sub-assembly with a detent shoulder which is engaged from behind by the detent element of the locking tang when the pipe segments are plugged into each other, the first and second sub assembly having respective terminal stop faces that limit the mutual displacement, and the resilient tang is received at a closed fit between the arms and wherein the elongated guide portion is guided by lateral guide faces of the arms.
