Abstract

The invention relates to a coupling point for central air-extraction systems, and comprises: a base (2), fixed either direct to the wall or to the open side of a pattress (20) and having a hollow cylindrical socket (3); a base-insert (5) whose rear face exhibits a protruding tubular element (6) which fits coaxially into the hollow cylindrical socket (3); a flat shutter (8) which slides transversely across the open front end of the tubular element (6), is provided at one end with a hole (9) of diameter no less than the internal diameter of the tubular element (6), and is guided by a retaining-component (11) fitted to the front of the base-insert (5); and an outer panel (12) fitted over the retaining-component (12).
