The invention relates to a device allowing electronic experiments to be carried out, which is constituted by a box made in two identical parts placed back to back, between which,according to the configuration of choice, connection bars equipped with clip contacts 1 and 2 on their two wide faces are arranged in bores 5. A housing fitted with edges 3 provided for this purpose receives a card bearing a front and back impression allowing the indexing of the bars on the back and of the electronic components to be used on the front, with, for the latter, the characteristics and the values. The connections to be made are also printed and can only be made with the desired contacts with respect to which the card is perforated. <IMAGE>
