Fastening device for electronic modules on a support rail

A device for fastening an electronic module on a support rail, comprising:

• a displaceable nose configured to encompass, together with a fixed nose provided on a rear face of a housing of the electronic module, a profile of the support rail;
• a slide, wherein the displaceable nose is configured as a clamping profile of the slide;
• mechanical anchors, wherein the device is mounted on the rear face of the electronic module by inserting the mechanical anchors in recesses on the housing of the electronic module;
• a spring mechanism configured to be braced against the housing of the electronic module and which causes the slide to be subjected to a force resulting in a clamping force of the device on the support rail, wherein
• an end of the slide opposite the displaceable nose projects beyond the housing of the electronic module for manual displacement of the displaceable nose, and
• the end of the slide has an elongated opening configured such that the slide is released from a stopped state by turning a screwdriver inserted into the opening.
