Connector for suspended metal ceiling framework and ceiling employing same

A connector for a ceiling framework formed of main beams and of cross beams, comprising:

• two parts that include a primary clip as a first part of the two parts and a secondary clip as a second part of the two parts, which are fastened to one another via a fusible part configured to melt at a temperature of a fire so as to cause the two parts to separate, wherein
• the connector is configured to make a connection between two beams among the main beams and the cross beams of the ceiling framework according to a stab-in system, such that the primary and secondary clips in a state fastened to one another are insertable through a same side of an aperture in one of the main beams or in one of the cross beams,
• the secondary clip is a three dimensional component that gives the connector thickness when the primary and secondary clips are fastened to one another, and this thickness is reduceable under load because of elasticity of the secondary clip, and
• the secondary clip includes a front part and a rear part, the front part being partially separated from the rear part by a slot and bent with respect to the rear part so that the front part diverges from a plane of the rear part by an angle, and the front part being shaped such that a very front of the front part is closer to the plane of the rear part and having a tapering shape on the very front.
