A holding frame for a plug-type connector is intended to have good heat resistance and a high level of mechanical robustness and, when installed in a metallic plug-type connector housing, enable protective grounding while at the same time being convenient to use, in particular during the replacement of individual modules. To this end, it is proposed to manufacture the holding frame at least partially from spring-elastic sheet metal. For this purpose, the holding frame can have a basic portion and a deformation portion, which are formed from different materials. The basic portion is used for fixing an accommodated module in a plane. The deformation portion can assume an insertion state and a holding state, wherein the insertion state permits insertion of at least one module into the holding frame in a direction transverse to the plane and an accommodated module is fixed in the holding state.
