Threaded clamping plug for interconnecting two implants of a spinal osteosynthesis instrumentation or other implants

A threaded clamping plug for providing an interconnection between two implants comprising:

• a first part having a first outer diameter and a second threaded part having a second outer diameter, said first outer diameter being different from said second outer diameter, said second threaded part coaxial with said first part and separated by a fracture initiating line, each part being provided with a print coaxial with each other, said first part having a roughened exterior surface and being adapted to permit screwing of said second threaded part into an implant up to a predetermined torque at which said fracture initiating line fractures between the two parts,
• wherein the print provided on said second part is an interior print configured for permitting an optional subsequent unscrewing of said second part, and
• wherein said fracture initiating line and said print of said second part are offset from each other along an axis extending between said first and second coaxial parts.

A threaded clamping plug for providing an interconnection between two implants comprising:

• a first part having a first outer diameter and a second threaded part having a second outer diameter, said first outer diameter greater than said second outer diameter, said second threaded part coaxial with said first part and separated by a fracture initiating line, each part being provided with an interior print coaxial with and unconnected with each other, said print of said first part being an interior print adapted to permit screwing of said second threaded part into an implant up to a predetermined torque at which said fracture initiating line fractures between the two parts,
• wherein the print provided on said second part is an interior print configured for permitting an optional subsequent unscrewing of said second part, and
• wherein said fracture initiating line and said print of said second part are offset from each other along an axis extending between said first and second coaxial parts.
