Assembly device for elongate components of osteosynthesis, especially spinal, equipment

An assembly device for connecting elongate components, said assembly device comprising:

• a body, said body having a threaded upper portion and two legs extending from said threaded upper portion with said two legs delimiting between them a channel for accommodating a first one of said elongate components, said legs being capable of deflection relative to one another with such deflection changing the dimensions of said channel from a securing position of said legs for securing said first one of said elongate components within said channel to a releasing position of said legs for releasing said first one of said elongate components from said channel,
• a portion of an outer periphery of said body defining a bearing surface,
• a transverse portion of said body defining a transverse aperture through said body with said transverse aperture being dimensioned for allowing passage of a second one of said elongate components;
• a ring fitting around said body and resting against said bearing surface when said legs are deflected to said securing position;
• and
• a nut being threadedly engaged with said threaded upper portion and exerting an axial force against said ring for retaining said second one of said elongate components within said transverse aperture and pressing said ring against said bearing surface.
