Abstract
Abstract The connecting section includes two metal sections held spaced from each other by at least one isolating bar having at least one recess extending longitudinally therein. Each of the metal sections are provided with at least one isolating bar-receiving groove and at least one grooved longitudinal member. Each of the grooved longitudinal members of the metal sections are fitted in a recess in the isolating bars by elastic deformation and each of the isolating bars have at least one slot opening to the adjacent metal section. The metal wire is sunk into the metal section and the isolating bar on deformation of the grooved longitudinal member. To provide a more uniform sinking of the metal wire in the slot over the entire length of the metal section, the metal wire (11) is made up of a linear core wire strand (12) and an outer wire strand (13) helically wound about the core wire strand (12) in a plurality of coil turns (14), adjacent turns of the outer wire strand being spread apart so that they do not contact each other (FIG. 3).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
266 words
In a connecting section comprising two metal sections and at least one isolating bar, said metal sections being held spaced from each other by said at least one isolating bar, each of said metal sections having at least one isolating bar-receiving groove and at least one grooved longitudinal member, each of said isolating bar-receiving grooves being bounded on one side by one of said grooved longitudinal members, each of said isolating bars having two opposing longitudinal edge regions, each of said longitudinal edge regions being provided with a longitudinally extending recess and at least one longitudinally extending slot, one of said longitudinal edge regions of said at least one isolating bar being received in one of said isolating bar-receiving grooves of one of said metal sections and the other of said longitudinal edge regions being received in one of said isolating bar-receiving grooves of the other of said metal sections, said grooved longitudinal members of said metal sections being deformed to fit in said receiving grooves of said at least one isolating bar so that said at least one isolating bar is held between said metal sections; and a metal wire with anchoring means sunk into each of said slots in said isolating bar, the improvement wherein the metal wire (11) with anchoring means consists essentially of a linear core wire strand (12) and an outer wire strand (13) helically wound about said core wire strand (12) in a plurality of coil turns (14), adjacent ones of said coils turns of said outer wire strand (13) being spread apart so as not to contact each other.
Claim 2
Dependent Claim
266 words
In a connecting section comprising two metal sections and at least one isolating bar, said metal sections being held spaced from each other by said at least one isolating bar, each of said metal sections having at least one isolating bar-receiving groove and at least one grooved longitudinal member, each of said isolating bar-receiving grooves being bounded on one side by one of said grooved longitudinal members, each of said isolating bars having two opposing longitudinal edge regions, each of said longitudinal edge regions being provided with a longitudinally extending recess and at least one longitudinally extending slot, one of said longitudinal edge regions of said at least one isolating bar being received in one of said isolating bar-receiving grooves of one of said metal sections and the other of said longitudinal edge regions being received in one of said isolating bar-receiving grooves of the other of said metal sections, said grooved longitudinal members of said metal sections being deformed to fit in said receiving grooves of said at least one isolating bar so that said at least one isolating bar is held between said metal sections; and a metal wire with anchoring means sunk into each of said slots in said isolating bar, the improvement wherein the metal wire (11) with anchoring means consists essentially of a linear core wire strand (12) and an outer wire strand (13) helically wound about said core wire strand (12) in a plurality of coil turns (14), adjacent ones of said coils turns of said outer wire strand (13) being spread apart so as not to contact each other.
Claim 3
Dependent Claim

Claim 8
Dependent Claim
22 words
The improvement as defined in claim 3, wherein said surface treatment includes coating at a temperature sufficient to activate said fusible adhesive.
Claim 9
Dependent Claim
25 words
The improvement as defined in claim 1, wherein said core wire strand and said outer wire strand each have a diameter of about 0.5 mm.
