Connectors for a framing system, wherein each of the connectors includes pairs of flanges that extend in parallel away from a base.

Modular structure including profile defining a prevailing development axis, and having a perimeter wall including a groove both extending parallel to the prevailing development axis, at least two edges delimiting the groove, wherein at least part of one is indented; connection for constraining more than one profile and including at least one connector including a flat body extending along a principal axis, including a first constraint guide to couple with a first constraint device and defining side walls and at least partially indented to block mutual translation between connector and profile along the main axis when the connector is in the groove, an obstruction element detachably constrainable to the body for interacting with the profile to block the connector with respect to the profile. The body includes a second constraint guide for housing at least part of a second constraint device to constrain the obstruction element and the connector.

A tensile membrane structure building system (10) including several standard extruded structural members (12) of the same cross-sectional profile. These standard structural members (12) have a rectangular cross-sectional profile with four sides (50.1-50.4) oriented at right angles to each other at four corners (52.1-52.4), each side including formations that define at least one channel (54) extending along a length of the structural members. By means of fasteners (80) that cooperate with the channels, standard structural members may be interlocked so as to form a framework (14). Each side of the standard structural member also include two slots (58) located on either side of the channel or channels towards the corners, the slots configured to receive and hold an edge of a membrane (16).
