Handle for a cognitive training device and cognitive training device comprising same

A cognitive training handle arranged to be connected by a longitudinal connecting means to a connection means on a ball, said handle further comprising adjusting means for adjusting the length of said longitudinal connecting means, said handle being characterized in that said adjusting means comprises:

• two side walls,
• a series of alternating retaining regions and passage regions between the two side walls,
• wherein the two side walls are connected to one another by a junction zone,
• wherein the retaining regions are regions where the two side
• walls are spaced apart from one another by a first dimension d at least smaller than a diameter of said longitudinal connecting means so as to jam said connecting means when the latter is introduced between the two side walls of said adjusting means, and
• wherein the passage regions are regions where the two side walls are spaced apart from one another by a second dimension d at least larger than said diameter of said longitudinal connecting means,
• the handle comprising an outer case, defined in at least two case parts, the case being arranged to at least partially house said adjusting means and, when said at least two case parts are connected to one another, has an outlet orifice for the connecting means,
• wherein the outer case comprises a groove extending over a complete periphery of the outer case, said outlet orifice for the connecting means directly opening onto said groove and said groove presenting a depth of groove and a width of groove at least larger than said diameter of said longitudinal connecting means to receive a free part of said connecting means in an adjusted manner.
