ABSTRACT:
A turnbuckle for connecting a hollow section is provided with a catch recess, with a carrier element having a clamping edge shoulder, the turnbuckle including a housing which fits within the hollow section. The housing has a longitudinal axis with an abutment pin fixed in the housing substantially transverse to the longitudinal axis. A clamping spring is movable in a translational manner within the housing, the clamping spring having a clamping finger part formed by two clamping fingers which are movable in mutually opposite directions substantially transverse to the longitudinal axis of the housing. Each clamping finger has a clamping hook end. A rotatable catch is provided for locking the housing with respect to the hollow section, the catch being engageable within the catch recess of the hollow section, and for moving the clamping spring between a starting stretching position and a final stretching position upon rotation of the catch, such that the clamping finger part engages with the abutment pin during movement from the starting stretching position to the final stretching position to force the clamping finger part to grip behind the clamping edge shoulder of the carrier element in the final stretching position. Each of the clamping spring and the rotatable catch includes a curvilinear catch link, and a cam follower bolt provides for immovably connecting the clamping spring and the catch together, the cam follower bolt being in both the clamping spring and the rotatable catch and engaging with each curvilinear catch link.
