1. A housing for a motor vehicle HVAC system, the housing comprising:
interconnectable housing parts; and
a groove delimited by a first and a second groove leg on a first housing part and a tongue on a second housing part,
wherein, to connect the housing parts, the tongue is disposed in the groove and
wherein the first groove leg in the fully inserted state of the tongue in the groove lies on a corresponding tongue-side bearing shoulder of the second housing part,
wherein the tongue is disposed on the second housing part such that the tongue-side housing wall has a geometry such that the second groove leg, which is formed longer than the first groove leg, in the fully inserted state of the tongue in the groove, lies on a corresponding bearing surface of the tongue-side housing wall of the second housing part,
wherein a tip of the tongue, in the fully inserted state of the tongue in the groove, is spaced apart from a base of the groove, and
wherein the second groove leg has a free end and the second groove leg tapers toward the free end, such that the second groove leg narrows towards the free end.
