Abstract: 1. A device for electrical connection of two electrical apparatuses such as an electrical protection apparatus associated to a controlled switch, said device being designed to electrically connect the output terminal(s) of one of the apparatuses, called the first apparatus, to the input terminal(s) of the other of said apparatuses, called the second apparatus, and comprising conductors housed in an insulating cover, the assembly extending along one of the faces of the two apparatuses, said above-mentioned input and output terminals comprising access openings on said faces, characterized in that the insulating cover (31) comprises a flap (39) designed to prevent access to the input terminal(s) (19, 20) of the second apparatus T when the connection device C is fitted while leaving access to the output terminal(s) (21, 22) of said second apparatus free. 2. The device according to claim 1, characterized in that, in the connection position, the flap (39) is designed to prevent access to the actuating means (27, 28) of the input terminal(s) (19, 20) of the second apparatus T and/or to the parts of conductors situated at the level of the opening (23, 24) of said input terminal(s) (19, 20). 3. The device according to claim 1 or 2, characterized in that the flap (39) is mounted articulated with respect to the cover (31). 4. The device according to any one of the claims 1 to 3, characterized in that the cover (31) being made of plastic material, the flap (39) is mounted articulated on the cover (31) by means of an integrated hinge (40) made of plastic. 5. The device according to any one of the claims 1 to 4, characterized in that it comprises clipping means (41) provided in part on the flap (39) and in part on the case of the second apparatus T, said means being designed to perform fixing of the flap (39) on the case of the apparatus. 6. The device according to any one of the foregoing claims, characterized in that it comprises on the one hand a plate (36) comprising conduction paths (32, 33), said plate (36) being able to be moved to face the above-mentioned face (12) of the second apparatus T and to receive the conductors (34, 35) in so far as their part extending facing said face (12) is concerned, the above-mentioned flap (39) being mounted on said plate (36). 7. The device according to claim 6, characterized in that it comprises separate conduction paths (37, 38) able to be moved to face the above-mentioned face (10) of the first apparatus D and to receive the conductors (34, 35) in so far as their part extending facing the first apparatus D is concerned. 8. An electrical apparatus housed in a case comprising a rear face for fixing to a mounting support such as a rail, a front face, two main faces by means of which the apparatus can be adjoined to another apparatus of the same type, and two opposite side faces, said apparatus being able to be connected to another electrical apparatus located up-line on said mounting support by means of a connection device according to any one of the claims 1 to 7, characterized in that it comprises at least one input terminal (19, 20) and at least one output terminal (21, 22), said terminals being situated on the same side of said support R, and that the input terminal(s) (19, 20) on the one hand and the output terminal(s) (21, 22) on the other hand are respectively arranged at two different depth levels of the case of the apparatus and are respectively staggered in the heightwise direction of the apparatus. 9. An electrical apparatus housed in a case comprising a rear face for fixing to a mounting support such as a rail, a front face, two main faces by means of which the apparatus can be adjoined to another apparatus of the same type, and two opposite side faces, said apparatus being able to be connected to another electrical apparatus located up-line on said mounting support by means of a connection device according to any one of the claims 1 to 7, characterized in that it comprises at least one input terminal (19, 20) and at least one output terminal (21, 22), said terminals being situated on the same side of said support R, and at least one control terminal (17, 18) situated on the other side of said support R. 10. The electrical apparatus according to claim 9, characterized in that the input terminal(s) (19, 20) on the one hand and the output terminal(s) (21, 22) on the other hand are respectively arranged at two different depth levels of the case of the apparatus and are respectively staggered in the heightwise direction of the apparatus. 11. The apparatus according to claim 8 or 10, characterized in that the input terminal(s) (19, 20) is(are) situated at the rear of the apparatus and at the level of one (12) of the side faces of the apparatus and the output terminal(s) (21, 22) is(are) situated at the front of the apparatus T and set back with respect to said side face (12) of the apparatus T. 12. The apparatus according to any one of the claims 8 to 11, characterized in that the input terminals and output terminals each comprise an access opening (23, 24) and (25, 26) for the conductors, said openings being situated respectively for the input terminals (19, 20) and the output terminals (21, 22) on two parts of lateral surfaces (12a, 12b) staggered in the heightwise and depthwise direction of the case. 13. The electrical apparatus according to any one of the claims 8 to 12, characterized in that the input terminal(s) and output terminal(s) comprise actuating means respectively situated for the input terminals and the output terminals on two parts of front face (4a, 4b) staggered in the depthwise and heightwise direction of the case. 14. The apparatus according to any one of the claims 8 to 13, characterized in that the first apparatus D is a circuit breaker and/or in that the second apparatus T is a remote-controlled switch or a contactor. 15. The apparatus according to any one of the claims 8 to 14, characterized in that the input terminals (19, 20) are staggered with respect to the output terminals (21, 22) in a direction parallel to the width of the case. 16. The apparatus according to any one of the claims 8 to 15, characterized in that the second apparatus is a single-pole remote-controlled switch, the above-mentioned cover only comprising a single electrical path.
