Modular structure and making process of said modular structure

A modular structure comprising at least:

• a profile defining a prevailing development axis, comprising at least a perimeter wall extending parallel to said prevailing development axis and including:
• a groove extending along at least part of said perimeter wall parallel to said prevailing development axis, and
• at least two edges arranged on opposite sides and delimiting said groove of which at least part of one of said edges is jagged;
• connection means capable of constraining more than said profiles and comprising at least one connector including:
• a flat body extending along a main axis, including at least a first constraint guide suitable to couple with a first constraint device and defining side walls extending alongside said main axis delimiting said body and at least partly indented so as to block reciprocal translation of said such as to block the mutual translation between said connector and said profile along said main axis, when said connector is inserted in said groove and said main axis is therefore parallel to said prevailing development axis,
• an obstruction element detachably constrainable to said body and capable of interacting with at least part of said profile, for blocking radial movement with respect to said prevailing development axis of said connector with respect to said profile;
• said body including a second constraint guide suitable to house at least part of a second constraint device configured to mutually constrain said obstruction element and said connector,
• wherein said obstruction element comprises at least a first constraint portion coupling to said first constraint device and a second constraint portion coupling to said second constraint device, and
• wherein said second constraint is capable of being constrained to said second constraint portion by resting at least partially on said second constraint guide.
