A joint for use in a piece of furniture or other furnishing item with a shoulder and a shelf, stably interconnected by the joint perpendicularly to each other, is maneuvered with an actuation and blocking system. The joint includes a pin with a fixing element, which becomes at least partially inserted in holes defined in the shoulder and the shelf, the pin having a side hole for receiving a shaped stem that extends from the actuation and blocking group of the joint. The actuation and blocking group has a 90 transmission between a maneuvering point, which is accessible from the front of the furniture, and the shaped stem, which is inserted in the side hole of the pin. Reciprocal retention elements, provided between the pin and the actuation and blocking group, withhold the pin in the hole of the shelf housing the pin.

An assembly/joining device (10) for parts or components of modular furniture and furnishing accessories of the shelf units, bookcases, cupboards, bed frames type and the like, including a pin (12) and a bushing (14) inserted in dedicated seats made in the components of the furniture to be joined and attached rigidly one with respect to the other, the pin (12) which includes a ferrule (24) elastically retractable internally to the pin apt to couple with the bushing (14) and co-operating with guide elements of the bushing (14) for a coupling/uncoupling between the pin (12) and bushing (14) during assembly/disassembly of the furniture parts.

A device for connecting two furniture parts, wherein the device comprises a housing arrangeable on a first furniture part and an eccentric element rotatably mounted in the housing. The housing is on one wall side flattened, and the flattened wall side of the housing has a continuous opening. The eccentric element is configured to cooperate with a connecting element, wherein the connecting element is arrangeable on a second furniture part, and wherein the connecting element can be coupled with the housing and the eccentric element such that the first and the second furniture part are fixedly connected to each other. The device is characterized in that the continuous opening in the housing on the flattened wall side is fully enclosed at the margin by wall portions.

A connection fitting for connecting two components has a housing, slide, bolt and control element. The control element is mounted in the housing rotatable about an axis extending obliquely to the bolt axis. The control element has a guide slot having a radially inwardly facing tightening contour and a radially outwardly facing blocking contour. When the control element is rotated out of the initial position in a first portion of the installation rotation, the control element pushes the slide by a stud guided in the guide slot into the front slide end position. In a second portion of the rotation, the slide is locked in the front slide end position by the blocking contour and the bolt is pulled radially inward by the tightening contour engaging behind the undercut, until, at the latest in the end position, the bushing has been spread apart by the spreading head.

A connecting assembly, includes: a reinforcing part having a connecting end and a mounting end positioned opposite each other, the end of the connecting end has a connecting passage, and the side surface of the connecting end has at least one deformation gap, a part of the connecting end is defined by the deformation gap to have at least one elastic part, the outer side surface of the elastic part has a fastening protrusion; the outer side surface of the reinforcing part has a mounting space connected to the connecting passage; a cam rotatably installed in the mounting space; and a plug, the plug has an inserting passage running through both ends of the plug, with one end of the plug inserted insert into the connecting passage from the connecting end.
