Clamping arrangement of an equipment module on a supporting rail and module for such an arrangement

An electrical or electro-optical equipment module adapted to be mounted on a rail serving as a support for a plurality of modules, said module including:

• a clipping arrangement for clipping an electrical or electro-optical equipment module onto a support rail adapted to receive a plurality of said modules, the arrangement comprising a rigid hook-forming first portion adapted to hook onto a first edge of the rail, and a catch-forming second portion which is adapted to hook onto a second edge of the rail under the action of a resilient return force and which is actuated remotely by means of leverage from a force-transmitter device comprising a rigid piece elongate in shape connected via a first hinge to a driver device and via a second hinge to the catch-forming second portion, it thus being possible to position the driver device remotely from said catch-forming second portion on the opposite side of the base zone for bearing against the rail from said catchforming second portion.
