Respect barrier for a museum environment

A respect barrier preventing public from getting too close to an object on display in a museum environment, the respect barrier comprising:

• a main bar,
• a secondary bar anchored to the main bar, the secondary bar comprising:
• a tubular end portion extending along a mounting axis at an end of the secondary bar remote from the main bar, and
• a through-hole made in the tubular end portion transverse to the mounting axis;
• and
• a fastening assembly for fastening the secondary bar to a wall, the fastening assembly comprising:
• a fixing plug, adapted to be fastened within a hole made in the wall,
• a tang, fastened on the fixing plug and protruding from the wall, extending along the mounting axis, configured to be inserted into the tubular end portion of the secondary bar,
• a flange, protruding from the tang and transverse to the mounting axis at one end of the tang adjacent to the fixing plug, configured to rest axially on an end of the tubular end portion of the secondary bar,
• a threaded hole in the tang and transverse to the mounting axis, and
• a screw, configured to be inserted into the through-hole and engaged by screwing into the threaded hole;
• wherein, prior to mounting the secondary bar on the tang, a distance in a direction of the mounting axis between the threaded hole and the flange is smaller than a distance in the direction of the mounting axis between the through-hole and the end of the tubular end portion of the secondary bar.
