PROBLEM TO BE SOLVED: To provide a connecting device for connecting the end parts of two profile members to each other mechanically and firmly in a detachable and recomposable state. SOLUTION: This device is composed of a grooved line piece 6, a strap 1 with an opening, and a screw 7. A profile member to be connected has a fitting groove 5 for receiving the grooved line piece 6. The strap 1 with the opening has a plurality of penetrating elements 3 on the lower side. These penetrating elements 3 are protruded from the surface so as to penetrate into material of the profile member by low temperature deformation technique by fastening the screw 7, thus forming a mechanically positive end connection part of two profile members. The penetrating elements 3 are formed as the cutting edge of a grater. |
