1. A device for supporting and removably fixing furniture shelves comprising a pin associated with a shelf and configured to be inserted in a hole formed in a side wall of a piece of furniture, said device being configured to be inserted in the shelf and comprising a casing, substantially flattened parallelepiped in shape, housing a carriage inside of which said pin terminating with a head is mounted, which is stressed by a compression spring, to protrude normally from the casing and so as to be able to re-enter completely into the casing with a linear displacement following a force exerted axially thereon,
wherein said pin has a body sliding linearly in the carriage, without substantial transversal play, whereon at least one slanting plane is provided, co-operating with a corresponding slanting plane provided on the casing to cause a transversal sliding of the carriage, in a direction perpendicular to the axis of the pin, simultaneously to an oblique movement of the pin through the action of said spring or following a transverse force acting on the pin with consequent exiting or re-entry of the pin in the casing.
