The invention relates to a device which makes it possible rapidly and reliably to join or separate two rings carrying keys, and making it possible for it to serve as an advertising support and as a case. It consists of two half-shells: one 1 carries, on one side, a ring 8 and, on the opposite side, has a receptacle 3; the other 7 carries, on one side, a ring 2 and, on the opposite side, has a plunger 9 with two wedges (keys) 10. In order to assemble the two half-shells 1 and 7, insert the plunger 9 right inside the receptacle 3 and rotate it by a quarter of a turn with the aid of the two rings 2 and 8, so that the wedges (keys) 10 are locked in the receptacle 3. In order to separate them, perform the operation in reverse. The device according to the invention may used in order to join and separate keys with different functions (boot, ignition, etc.), in order to form an advertisement by means of printing on the casing (initials, etc.), in order to form an advertisement by means of the object (ball, etc.), and in order to serve as a case (various pills, miniature product, etc.). <IMAGE>
