A connector for detachably connecting profiles includes a housing; a first and a second clamping component, each comprising at their ends a clamping hook; an activation mechanism adapted to shift the first and second clamping components concerning the housing; a first and a second pair of guide components adapted to define a trajectory of the first and second clamping components, respectively, during the shift, so that at least during a part of the trajectory the distance in the transverse direction Y between the clamping hooks is varied, and at least during a part of the trajectory the distance in longitudinal direction X between the housing and the clamping hooks is varied.

Profile connector for connecting a first and a second profile bar (3, 4), made from a light metal alloy, with a body (5) which can be accommodated in an undercut elongated groove (34) in the second profile bar (4) and has at least one bracing leg (7) for bracing against an undercut (9, 10) of the undercut elongated groove (34) of the second profile bar (4), and an anchor bolt (13) which is accommodated in a through opening (12) that is created in the body (5) and extends at right angles to a longitudinal extension of the body (5), which anchor bolt has an anchor bolt head and fixes the profile connector (1) frontally, on the first profile bar (3), and with a first clamping screw (22) accommodated in an internal threaded opening (20) provided inside the body (5) and extending at an angle to a longitudinal center line (L.sub.A) of the through opening (12), which clamping screw serves to displace the body (5) along the anchor bolt (13) away from the anchor bolt head (19) towards the first profile bar (3) by tightening the first clamping screw (22) in the internal thread of the first internal threaded opening (20), thereby bracing the first clamping screw (22) on the anchor bolt (13), wherein a forming geometry (29) is conformed and arranged on the body (5) for shaping frontally into the first profile bar (3) by tightening the first clamping screw (22) to create a positive locking connection between the body (5) and the first profile bar (3).

The angle connector (100) has two free ends (110, 120) aligned perpendicular to each other, for the purpose of being inserted into an associated cavity of a supporting profile (10, 20), such that at every free end (110, 120) of the angle connector, a passive means of fixation (131, 132, 133) is provided, via which from one outer side of the supporting profile (10, 20), the respective end of the angle connector can he detachably connected to the associated supporting profile by way of a complementary active fixation element (40, 44). Between the free ends that are aligned perpendicular to each other, a corner element is provided, with profile elements (111, 112) compatible with the supporting profiles provided on its two outer sides that are positioned perpendicular to each other, respectively reaching until the height of the associated surface (55) of the corner element (110).

A kit for assembling furniture, which comprises at least one panel, which defines externally two mutually opposite greater faces which are mutually joined by four side faces, at least one joining batten, and means of coupling between the panel and the batten; the coupling means comprise: a collar, which can be inserted into at least one first seat provided at one of the greater faces, and at least one pin, which can be partially inserted into at least one second seat provided at one of the side faces. The second seat leads to the first seat, in order to allow the introduction of a first end portion of the pin into a transverse hole of the collar, which is previously inserted into the first seat, with consequent definition of at least one intermediate configuration of assembly.
