Ball-game racket, particularly a tennis racket

A ball-game racket, particularly a tennis racket, said racket comprising:

• a hollow, outwardly closed racket body which forms a racket handle and a racket frame including a racket head,
• a stringing formed of intersecting string lengths on the racket head and defining a stringing plane,
• openings in said frame, said openings being provided with sleeves which close the frame tightly off from the outside at the openings, said sleeves having sleeve openings through which the string lengths are passed from the inside of the frame to the outside of the frame and vice versa for obtaining a string attachment holding the stringing on the frame, and
• for at least a part of the string lengths, said string attachment is such that said string lengths, have, on the inside of the frame, at least in an axial direction perpendicular to the stringing plane, a mobility which is substantially greater than a corresponding mobility of the outer side of the racket frame, and
• for said string attachment, each of the corresponding sleeves having a sleeve opening which widens in cross section towards the inside of the racket frame and has, on the inside of the racket frame, at least in an axial direction perpendicular to the stringing plane a size which is greater than the cross section of the string lengths.
