A racket for ball games, in particular tennis, comprises a stringing system in the form of individual strings. The individual strings are each held in the racket frame by means of rivet sleeves, with the rivet heads bearing against the outer edges of the holes in the racket frame. In the event of a string breaking, there is no reaction on the adjoining strings, and only the broken string has to be changed. The individual strings which are provided for the first stringing or for replacement stringing have a fixedly disposed rivet sleeve at one end. In addition there is a loose rivet sleeve which is intended for being pushed on and connected after the string has been inserted into oppositely disposed holes. In addition described is a stringing device of simple design, by means of which individual strings can be easily replaced even by technically unskilled persons.
In combination, an individual string for fitting in a racket used for ball games, in particular tennis, said string having first and second rivet sleeves mounted adjacent opposite ends, a racket having a frame with inside and outer surfaces and aligned holes formed on opposite sides of said frame for receiving said string passed therethrough by means of a stringing device, and a stringing device including tensioning means for exerting tensile stress on said individual string and including a contact portion adapted to be mounted on said outer surface of said racket frame, a holding portion for engaging said inside surface of said racket frame, said holding portion including means movable relative to said contact portion for adjustment to accommodate frames of different thicknesses, prestressing means for said string on said contact portion including an actuating lever having clamping means for holding tension on said string, measuring means for indicating the level of prestressing achieved, and means for compressing said second rivet sleeve tightly on said string while said string is maintained in a prestressed condition;
