The seal includes a first sealing element mechanically connected to the protection device and a second sealing element mechanically connected to the connector. The first sealing element engages the second sealing element to connect the protection device to the connector. ## Claims ### Claim 1 A connection device, comprising: a protection device configured to protect a cable; a connector configured to electrically connect the connection device to an external electrical connection; and a seal connecting the protection device to the connector, the seal including a first sealing element and a second sealing element, wherein the first sealing element is mechanically connected to the protection device and the second sealing element is mechanically connected to the connector, the first sealing element engages the second sealing element to connect the protection device to the connector, wherein the second sealing element is movable with respect to the connector and the first sealing element when the first sealing element engages with the second sealing element. ### Claim 2 (depends on 1) The connection device of claim 1, wherein the first sealing element has a projection and the second sealing element has a housing. ### Claim 3 (depends on 2) The connection device of claim 2, wherein the projection is inserted into the housing to connect the protection device to the connector. ### Claim 4 (depends on 3) The connection device of claim 3, wherein the housing has an assembly slot receiving a lug of the projection. ### Claim 5 (depends on 4) The connection device of claim 4, wherein the first sealing element exerts pressure on the protection device and the connector by engagement of the lug with the assembly slot. ### Claim 6 (depends on 1) The connection device of claim 1, wherein the connector has a lateral groove receiving the second sealing element. ### Claim 7 (depends on 1) The connection device of claim 1, wherein the connector has an upper groove receiving the first sealing element. ### Claim 8 (depends on 1) The connection device of claim 1, wherein the first sealing element is formed of a plastic material and the protection device is formed of an elastic material. ### Claim 9 (depends on 1) The connection device of claim 1, wherein the connector includes a retention element holding the second sealing element with respect to the connector. ### Claim 10 (depends on 1) The connection device of claim 1, wherein the connector has an upper surface supporting a lower surface of a flange of the protection device. ### Claim 11 (depends on 10) The connection device of claim 10, wherein the upper surface of the connector has a plurality of ridges and the lower surface of the flange has a plurality of ridges corresponding to the ridges of the connector. ### Claim 12 (depends on 10) The connection device of claim 10, wherein the upper surface of the connector is a flat surface. ### Claim 13 (depends on 1) The connection device of claim 1, wherein the second sealing element is movable with respect to the connector and the first sealing element in a direction transverse to a connection direction of the connector when engaging with the first sealing element. ### Claim 14 (depends on 13) The connection device of claim 13, wherein the first sealing element has a projection and the second sealing element defines a slot receiving the projection, the slot extending in the direction transverse to the connection direction of the connector for permitting movement of the second sealing element relative to the first sealing element along the slot. ### Claim 15 A connection device, comprising: a protection device configured to protect a cable; a connector configured to electrically connect the connection device to an external electrical connection; and a seal connecting the protection device to the connector, the seal including a first sealing element having an opening receiving the protection device and a second sealing element, wherein the first sealing element is mechanically connected to the protection device and the second sealing element is mechanically connected to the connector, the first sealing element engages the second sealing element to connect the protection device to the connector. ### Claim 16 (depends on 15) The connection device of claim 15, wherein the second sealing element is movable with respect to the connector and the first sealing element in a direction transverse to a connection direction of the connector when engaging with the first sealing element. ### Claim 17 A method for connecting a protection device to a connector to form a connection device, comprising: connecting a first sealing element to the protection device; connecting a second sealing element to the connector; and engaging the first sealing element with the second sealing element to connect the protection device to the connector, the second sealing element moved with respect to the connector and first sealing element when engaging with the first sealing element. ### Claim 18 (depends on 17) The method of claim 17, wherein the engaging step includes inserting a projection of the first sealing element into a housing of the second sealing element. ### Claim 19 (depends on 18) The method of claim 18, wherein the projection is capable of sliding with respect to an assembly slot of the housing. ### Claim 20 (depends on 17) The method of claim 17, wherein the protection device is configured to protect a cable and the connector is configured to electrically connect the connection device to an external electrical connection.
