The invention relates to a profile connecting system, comprising profile bars and connecting elements. The profile bars (30, 31) nave at least one axial elongated hole (4) and on the profile outer sides slots for nut block connections. In order to be able to assemble profile connections with minimal material and labour expenditure and in order to be able to avoid premachining operations on profile bars using machine tools and at the same time be able to transmit large forces, it is proposed to insert and fix an abutment, for example a threaded insert (22), in a self-cutting manner into the bore of an axial elongated hole (4) in a first profile bar (30). Adjacent to the installation length (32) of the threaded insert (22) and of the head of a screw (28), an axially running wrench opening (35) is to be provided in the tubular body (7) of the axial elongated hole (4). The length and width of the wrench opening (35) is to permit guidance therethrough of a socket wrench (33), with joints or with a substantially spherical socket wrench head (34) with flats, at an insertion angle to the longitudinal axis of the profile bar (30) and the coupling of the socket wrench to the head of the screw (28).
