Module with Housing for Mounting Rail

A module with housing, comprising:

• a first retaining means for fixing to a mounting rail, the first retaining means being designed such that it is connected in a form-fit manner to a first clamping means of the mounting rail;
• a second retaining means for fixing to the mounting rail, the second retaining means having a tensioning means and an anchoring means, the tensioning means being rotatably disposed about a pivot point disposed on the housing, wherein the tensioning means interacts with the anchoring means such that, by rotation of the tensioning means, the anchoring means is latched to a second clamping means of the mounting rail,
• wherein the anchoring means has a guiding means which is in engagement with a guiding point disposed on the housing, said guiding means being implemented as a link guide with a curved run for controlling the movement of the anchoring means.
