1. An electrical connector housing for connecting at least one cable lug to a threaded terminal of an electrical device, including for each lug, a tubular wall and an intersecting channel, the tubular wall having a hole for receiving a screw for retaining a lug in a threaded terminal, which tubular wall has a lateral slot communicating with the channel and designed to allow a lug to penetrate the hole from the channel, the tubular wall having at one end a lower opening for receiving the threaded terminal into the hole, whereby the lug may be connected to the threaded terminal, and the tubular wall having at an opposite end an upper opening designed to allow the passage of a tool for the screw, the size of the upper opening of the hole at its widest point being strictly less than the size of the hole at its widest point, said opening being designed so as to allow the passage of the tool and having a section which is less than the section of a human finger. 2. The housing according to claim 1, wherein the size of the upper opening of the hole taken at its widest point is less than or equal to 12 mm. 3. The housing according to claim 1, further comprising a cover provided with sealing means designed to close the hole in a sealed manner. 4. The housing according to claim 3, wherein the lower opening of the hole has sealing means designed to co-operate with the device to be connected and the cover has fixing means designed to fix the cover to the device to be connected, so as to keep the housing fixed to the device via the cover in a sealed manner. 5. The housing according to claim 3, wherein the cover and/or the housing have contact means designed to cut-off current upstream of the connector when the cover is removed. 6. The housing according to claim 1, wherein the slot of the hole opens onto a channel designed to receive the cable of the corresponding lug, said channel being provided with sealing means to provide tightness between the cable and the housing. 7. The housing according to claim 6, wherein the channel has fixing means at its end for a sealing plug for passage of the cable in the housing and tight closure of the end of the channel. 8. The housing according to claim 1, wherein the hole has protrusions on an internal surface for maintaining the screw at a predetermined height so as to retain the screw between the end of the hole which has the upper opening and the slot, so as to keep the screw spaced apart from the slot when the lug is inserted. 9. The housing according to claim 1, wherein the housing is provided with a fixing screw, the end of said fixing screw, which is opposite a screw head, having a tip covered with a cap made from insulating material. 10. The housing according to claim 1, further comprising a cover wherein the housing and/or the cover is made from a plastic material which is at least partially metallised so as to provide electrical shielding for contents of the housing. 11. A process of connecting an electrical connector for connecting at least one cable lug to a threaded terminal of an electrical device including a housing according to claim 1, comprising the steps of: introducing a retention screw via the lower opening with a tip presented towards the upper opening;introducing a lug into the slot provided to this end;presenting the connector opposite the terminals of the electrical device to be connected;introducing a tool via the upper opening;pushing the screw by means of the tool until the screw engages in the thread of the terminal; andfixing the lug to the terminal by tightening the screw by means of the tool. 12. An electrical connector housing for connecting at least one cable lug to a threaded terminal of an electrical device, including for each lug, a hole for receiving a screw for retaining a lug in a threaded terminal, which hole has a lateral slot designed to allow a lug to penetrate the hole, a lower opening for connecting the lug to a threaded terminal and an upper opening designed to allow the passage of a tool for the screw, the size of the upper opening of the hole at its widest point being strictly less than the size of the hole at its widest point, said opening being designed so as to allow the passage of the tool and having a section which is less than the section of a human finger, and a cover provided with sealing means designed to close the hole in a sealed manner. 13. The housing according to claim 12, wherein the size of the upper opening of the hole taken at its widest point is less than or equal to 12 mm. 14. The housing according to claim 12, wherein the lower opening of the hole has sealing means designed to co-operate with the device to be connected and the cover has fixing means designed to fix the cover to the device to be connected, so as to keep the housing fixed to the device via the cover in a sealed manner. 15. The housing according to claim 12, wherein the cover and/or the housing have contact means designed to cut-off current upstream of the connector when the cover is removed. 16. The housing according to claim 12, wherein the slot of the hole opens onto a channel designed to receive the cable of the corresponding lug, said channel being provided with sealing means to provide tightness between the cable and the housing. 17. The housing according to claim 16, wherein the channel has fixing means at its end for a sealing plug for passage of the cable in the housing and tight closure of the end of the channel. 18. The housing according to claim 12, wherein the hole has protrusions on an internal surface for maintaining the screw at a predetermined height so as to retain the screw between the end of the hole which has the upper opening and the slot, so as to keep the screw spaced apart from the slot when the lug is inserted. 19. The housing according to claim 12, wherein the housing is provided with a fixing screw, the end of said fixing screw, which is opposite a screw head, having a tip covered with a cap made from insulating material. 20. The housing according to claim 12, further comprising a cover wherein the housing and/or the cover is made from a plastic material which is at least partially metallised so as to provide electrical shielding for contents of the housing.
