The invention relates to implements for practicing tennis. It comprises three small baskets for one ball (sheet 3/3), two balls (sheet 1/3) and three balls (sheet 2/3) as spare balls. The baskets for two and three balls (sheets 1/3 and 2/3) have a similar structure, and are differentiated only by the length of the central portion (2). They are formed by a cylindrical body comprised of a netting central part (2), an upper ring (1) and a lower ring (3) the assembly being fixed by a unit construction on a base plate (5, 6). On the lower ring there is secured the retaining and outlet system for the balls, consisting of two hinge valves (8) actuated and retained in a normal-close position by angular actions spring (9). The baskets for two and three balls represent modules to be assembled in manufacturing as units of two and three parts, capable of containing a reserve from four to nine balls, provided for training and pleasure games. The basket for one ball comprises a body having a cross section shaped as a coconut palm of which the bottom is cut (1), integrally fixed by manufacture on a rectangular base plate (2). It is provided for point counting games. In use, the baskets are fixed on the abdomen by means of an elastic belt, attached arround the waist, the base plate giving them a perfect stability.
