The invention concerns a heating system or air conditioning system for vehicles having a heater box and an operator unit which has to be arranged separately from the heater box in the passenger compartment. In order to hold the operator unit on the heater box until the point of final assembly and for the purpose of adjusting the operator unit during preassembly, a two-part assembly aid element is provided, of which one part is firmly connected to the heater box and the other part is firmly connected to the operator unit so that the operator unit is fixed so that it cannot be varied until final assembly on the heater box. In order to configure the assembly aid element so that it can be manufactured simply and at low cost, its two parts are formed by two plug-in parts of a plug-in connection which can be pushed one into the other and a clip-type interlock is included in the plug-in connection. The interlock engages automatically due to axial pressure on the plug-in parts and is released by axial tension on one of the plug-in parts. |
