The clamping device has an insert core (2) which can be inserted and fixed in one of the profiled pieces (1). The insert core (2) comprises an axially moving anchor bolt (7) whose head is designed in order to engage behind a longitudinal groove in the other profiled piece (19). A screw which is guided in a threaded bush (4) engages via a system of inclined surfaces (14, 15) in the anchor bolt (7) in order to displace the latter axially. The anchor bolt (7) carries a rod in order to support plurality of retaining pieces (17, 17') such that they can pivot. These retaining pieces and the two inner walls of the insert core (2) surround a second system of inclined surfaces (24, 26) which, in the event of an axial movement of the anchor bolt (7) against a spring (6), cause pivoting of the retaining pieces (17, 17') in order to engage behind the longitudinal groove with in each case one tab (21) which is present on the free end regions of the retaining pieces. The thread of the screw and of the threaded bush (4) may have an increased pitch. The threaded bush (4) may be provided with a lateral hole, which is expanded on the sides, for guiding the bolt (7). …<IMAGE>… |
