A holding frame for a heavy plug-type connector can receive identical and/or different plug-type connector modules. The holding frame comprises a main body which has two side parts which lie opposite one another, and at least one fixing clip which is held at least on a side part, and by way of which the plug-type connector modules can be fixed within the main body. The at least one fixing clip has at least one holding arm which moves parallel to the plane of the side parts during the introduction of a plug-type connector module into the holding frame. As a result, plug-type connector modules can be introduced into the holding frame particularly simply and even in the installed state of said holding frame. At the same time, the holding frame variant which is shown here is more stable than the previously known holding frames which have the same functionality.
