Abstract: A clamp includes a flat strip whose ends coil onto themselves in the shape of a ring and are fastened by a retaining pawl and a hook that are coupled in a retaining bridge and an orifice, respectively, for a further constriction of the clamp, that is brought to its optimal tightening position by pliers or other appropriate tools through tightening and deformation of the clamp bridge, which bridge is provided with a deformation that imparts said bridge greater inertial resistance and that in such tightening and advance movement of one end underneath the other an engagement has been provided for both ends by a tongue located at one end and a recess at the other end of the strip.

Abstract: The present invention discloses a clamp of the type comprising a flat strip (1) whose ends coil onto themselves in the shape of a ring and are fastened by means of a retaining pawl (2) and a hook (3) that are coupled in a retaining bridge (6) and an orifice (7), respectively, for a further constriction of the clamp, that is brought to its optimal tightening position by means of pliers or other appropriate tools through tightening and deformation of the clamp bridge (12), which bridge is provided with a deformation (15) that imparts said bridge greater inertial resistance and that in such tightening and advance movement of one end underneath the other an engagement has been provided for both ends by means of a tongue (14) located at one end and a recess (13) at the other end of the strip.

Abstract: Improvements to the construction of metal brackets with screw for the clamping or tightening thereof, the vertices of the extremities of the two arms of the front cross-bar at the body-tunnel entrance are enlarged, and a space is provided for the housing thereof into the screw body, with concentric bearing flange and double clamping tailpiece of the two ends of the metal strip coiled from the tunnel base being substituted by a transverse monotailpiece which is rabated to the opposite side, with a threaded tongue for clasping purposes, and one of the extremities of the strip having two juxtaposed drawn pieces, one in the upper surface and the other one in the lower surface of crimping with the edge of the transverse monotailpiece, the upper one impeding the excessive elevation of the proper extremity.

Abstract: A sheet metal clip with opposed overlapping first and second ends includes a guide tongue integral with the first end and receivable within an integral chamber adjacent the second end. A pair of integral projecting columns adjacent the first end are received through two holes formed adjacent the second end and closely conform thereto to retain the overlapped ends against longitudinal and rotational movements.
