The invention relates to a tubular adapter for clamping connection with the end of a tubular part (4) of a modular prosthesis, said adapter consisting of an axially slotted connecting sleeve (2) circumferentially clampable by means of a clamping bolt or the like and intended to receive tube end (4), with one end of said sleeve abutted by an annular coupling section (3) preferably having on its circumference four equally spaced threaded holes (5), each hole being designed to receive a coupling and adjusting bolt (clamping bolt) and having an annular ball socket (6) provided endwise to engage a ball collar of an adjusting core, said socket extending in the coupling position on a projection designed as a multi-surface pyramid into the clamping area of the clamping bolts. To improve the connection between the tubular adapter and the tubular part, it is proposed according to the invention that free end section (7) of connecting sleeve (2) opposite coupling section (3) be provided on its inner annular surface with a plastic clamping cuff (8). |
