A connecting device having a hollow-body-like plug-in part which is of variable outer circumference and which interacts with a fixing device which is at least partially insertable into the plug-in part, wherein the fixing device is connectable to an actuation section which projects out of the plug-in part. Here, the plug-in part, with the fixing device inserted therein and with the actuation section connected thereto, has the minimum external shape thereof in terms of the dimensions thereof when the actuation section is in a rest position. The actuation section is moved by means of axial or radial movement relative to the plug-in part into a working position in which the plug-in part has the maximum external shape thereof in terms of the dimensions thereof, wherein the plug-in part has a closed shape on its side situated opposite the insertion side of the fixing device.

A tension connector connecting two components includes a bolt which has a bolt shaft and a bolt head. An eccentric lever has a bearing pot with a pot opening and with a pot interior which is formed as a pivoting bearing and by means of which the eccentric lever can be or is mounted on the bolt head so as to be pivotable about a pivot axis between a starting position and a tensioned position. The bearing pot has a slot for the bolt shaft, extending from the pot opening against the tensioning direction and, along the slot, has an outer contour which is eccentric relative to the pivot axis.

A spreading connector for connecting two furniture parts, including a built-in pot having a pot bottom, the pot being pressable, pot bottom first, into a housing bore of a first of the furniture parts. The pot further has a hollow-cylindrical pot wall that has a wall opening and at least one spreading tab that is cut free in the hollow-cylindrical pot wall and is pivotable about an axis running tangentially to the hollow-cylindrical pot wall. A tightening element is rotatably mounted inside the built-in pot for tightening a fastening bolt of a second of the furniture parts which passes through the wall opening. The tightening element has an outer eccentric surface for spreading the at least one spreading tab. The at least one spreading tab has a free tab end that extends in an axial direction away from the pot bottom.

Connection device for two furniture parts which have to be interconnected, with a first connection portion which is realized at least as a spreading system and which is intended for being provided in a recess in a first furniture part, with a second connection portion which is intended for extending outside of the recess for cooperating with a second furniture part in this manner, as well as an activation mechanism for activating the spreading system, wherein the spreading system comprises at least two mutually rotatable parts, a first part and a second part, respectively, wherein the mutual rotation of which, in function of the realized mutual angle position, effects a spreading effect.
