Profile-connecting device

A profile-connecting device for connecting two profile bars of which a first profile bar having an end side which abuts a longitudinal side of a second profile bar, at least an outer longitudinal side of the second profile bar which is directed toward the end side of the first profile bar and at least one outer longitudinal side of the first profile bar having an undercut groove, said profile-connecting device comprising:

• a clamping unit having at least two clamping elements which are spread apart by a first threaded unit, said clamping unit, at least in certain regions, having an outer contour which is clampable in the undercut groove upon being widened by the first threaded unit,
• a second threaded unit which engages the groove of the second profile bar from a rear position,
• the clamping elements being spread apart from a substantially closed position to an open spread-apart position so as to be clamped in the undercut groove of the first profile bar by the first threaded unit which is introduced into the clamping unit, being screwed into the second threaded unit, and a connection between the first and second profile bars being produced in conjunction with the threaded unit, via the first threaded unit,
• wherein the clamping unit has a base plate with a width (B) which corresponds to the groove width (B) of the profile bar, and said clamping elements are integrally formed with the base plate, directly abutting with the outside of the latter such that, in the substantially closed position, the clamping unit is at least pushable into the groove of the first profile bar from a front side of the first profile bar.
