1. An automated tightener for a wet mateable connection assembly comprising a first and a second watertight case, the automated tightener bearing a fixing assembly and comprising a first and a second sliding portions arranged in a parallel lay, connected together by a push/pull actuator substantially orthogonal thereto, each sliding portion being provided with operable engagers, wherein each sliding portion comprises two standing plates substantially orthogonal to the parallel lay of the sliding portion and spaced by a spacing plate. 2. The automated tightener according to claim 1, wherein the push/pull actuator is connected to the spacing plates of the sliding portions. 3. The automated tightener according to claim 1, comprising guides for leading the reciprocal movement of the two sliding portions. 4. The automated tightener according to claim 3, wherein the guides are fixed onto said standing plates of one of the sliding portions and engaged with retaining elements of an other sliding portion. 5. The automated tightener according to claim 3, wherein the guides are arc shaped. 6. The automated tightener according to claim 1, wherein the operable engagers are provided across the standing plates of each sliding portion. 7. The automated tightener according to claim 1, wherein the operable engagers are movable in opposite directions, substantially parallel to spacing plates. 8. The automated tightener according to claim 1, wherein the operable engagers of a sliding portion are operated jointly by a single engaging actuator. 9. The automated tightener according to claim 1, wherein the fixing assembly comprises a power screw-driver tool for connecting the watertight cases by bolts. 10. The automated tightener according to claim 1, wherein the automated tightener is remotely operated. 11. A method for underwater fastening a first watertight case to a second watertight case of a wet mateable connection assembly by an automated tightener, wherein the first watertight case is provided with an array of spaced coupling means; and the automated tightener bears a fixing assembly and comprises a first and a second sliding portion; comprising the steps of: associating the automated tightener with the first watertight case;engaging the first sliding portion to the first watertight case;locking a coupling means of the array to the second watertight case by operating the fixing assembly;distancing the second sliding portion from the first sliding portion;engaging the second sliding portion to the first watertight case;disengaging the first sliding portion from the first watertight case;approaching the first sliding portion to the second sliding portion; andrepeating the steps up to a completion of tightening of the first watertight case to the second watertight case. 12. The method according to claim 11, wherein engaging the first and the second sliding portions to the first watertight case comprises engaging an operable engager of the automated tightener with a coupling portion of the first watertight case. 13. The method according to claim 12, wherein the coupling portion of the first watertight case is a flange. 14. The method according to claim 11 wherein the array of spaced coupling means is arranged on a flange of the first watertight case. 15. The method according to claim 11, wherein engaging the first sliding portion or the second sliding portion to the first watertight case comprises engaging two operable engagers with two axially spaced coupling portions arranged on the first watertight case. 16. The method according to claim 11, further comprising removing the automated tightener from the wet mateable connection assembly after tightening completion. 17. The method according to claim 16, comprising connecting a scaffolding to the automated tightener, disengaging both the first sliding portion and the second sliding portion from the first watertight case and hauling the scaffolding together with the automated tightener connected thereto. 18. The method according to claim 11, wherein associating the automated tightener with the first watertight case comprises firmly attaching a scaffolding to the first watertight case while keeping the first sliding portion and the second sliding portion disengaged from the first watertight case and keeping the automated tightener connected to the scaffolding, sinking the scaffolding and the first watertight case connected thereto. 19. The method according to clam 18, wherein associating the automated tightener with the first watertight case comprises sinking the scaffolding and the automated tightener connected thereto and positioning the scaffolding over the first watertight case.
