The fourth connector 52 is integrally connected to the second housing side wall 17. In the present case, the fourth connector element 52 surrounds the third connector element 50 at least partially. The third male connector 50 and the fourth male connector 52 cooperate in the assembled state to prevent movement of the retainer 10 relative to the second housing sidewall 17 in the longitudinal direction of the housing unit 14.

The further plug-in connection units are at least substantially identical in construction to the first plug-in connection unit 42 and the second plug-in connection unit 44, so that a previous description can also be applied to the further plug connection units, which are assigned in particular to further holding elements 12. Alternatively, plug connection units could also be designed differently from one another. In this context, for example, it is conceivable that a first connector unit is provided for mounting in a mounting direction, which is arranged perpendicular to a main extension plane of a housing unit, while a second connector unit for mounting in a further mounting direction, which is arranged parallel to the main extension plane of the housing unit is. In addition, it is conceivable to arrange a plug connection unit only in the region of a first housing side wall or a second housing side wall.

Further, the holding elements 10, 12 are configured such that in the assembled state respective end faces of the holding elements 10, 12 abut the first housing side wall 16 and the second housing side wall 17, in particular a movement of the holding elements 10, 12 relative to the housing unit 14 in a transverse extension direction the housing unit 14 to prevent.

In addition, the holding elements 10, 12 are in the mounted state on the support surface 22 and the further support surface 24, in particular to prevent movement of the holding elements 10, 12 relative to the housing unit 14 in a height direction of the housing unit 14 at least partially.
