Component connecting means especially flange connecting means

A connector for securing a first workpiece with a first thickness having a first bore through said first thickness to a second workpiece having a second thickness and a second bore through said second thickness, comprising:

• a tensioning sleeve having an introduction end and a second end, said introduction end introduced through said first bore into said second bore wherein said first and second bore are in an aligned relationship;
• at least one slot running axially along said tensioning sleeve;
• a pin bore axially disposed along the longitudinal axis of and within said tensioning sleeve;
• a stop integral with said second end of said tensioning sleeve having a contact face for abutting said first workpiece;
• a further collar integral with said introduction end having a supporting face;
• a tensioning pin disposable within said pin bore for radially expanding said further collar to a diameter larger than said second bore and for displacing said further collar supporting face into abutting relation to said second workpiece whereby the axial length of said tensioning sleeve between said second collar supporting face and said stop contacting face is increased due to insertion of the pin to a length compressively assembling said first and second workpieces.
