Abstract
A connector for detachably joining one profile section to another in a framework assembly comprises a housing having a bottom part and a lid connected to one another by means of snap-lock coupling elements. The housing is insertable into a longitudinal recess at one end face of a horizontal profile section. A latch is slidably disposed in the housing and has, at an end projecting from the housing, a hook for engaging an inwardly facing surface of a vertical profile section. At an end opposite the hook, the latch has a rectangular aperture traversed by a substantially cylindrical eccentric pin projecting from the housing of the connector into a transverse bore in the horizontal profile section. The eccentric pin is outwardly biased by a spiral compression spring disposed on a side of the latch opposite the hook and opposite an incline disposed on the inner side of a housing portion and engageable with a bent segment of the latch for producing a transverse motion of the hook during a terminal phase of a longitudinal motion of the latch.
