Abstract

The invention provides an assembly for a motor vehicle. The assembly comprises: a retaining body (30) with a guide groove (32) having a front zone (34) and a rear zone (36); a front heat exchanger (24) with an adjustment groove (44) having a first segment (46) and a second segment (48); a connecting shaft (38) having a first section (40) in the front zone of the guide groove (32), and a second section (42) in the first segment of the adjustment groove to arrange the heat exchanger in a first position or in a second position distant from the first position. Fastening means (50) lock the second section (42) in the adjustment groove (44). During a frontal collision, the front heat exchanger (24) moves backward, displacing the connecting shaft (38) from the front zone (34) to the rear zone (36).
