Abstract

A support rail on which a plurality of housings, which can be strung together and which are equipped with electrical contact elements and/or functional elements, can be arranged is mounted onto a mounting base in a mounting position, even in a state in which the housings have already been strung onto the support rail prior to the support rail being mounted. The support rail is retained by two or more latching devices which are placed in position on the mounting base prior to the support rail being mounted. The latching devices and the support rail are configured such that the support rail can be placed onto the latching device and locked onto it without using any tools. The latching device has a base section has a cross-section relative to the mounting position on the mounting base which corresponds to a U rotated by 180°, The base section is divided into a horizontal base bar and two side bars perpendicular thereto and the latching element is supported on the mounting base as a thrust bearing via the two side bars.
