megane scenic 2005 dci1.5 wont start?

i think i have found the fault on my scenic it wont start i tried bumping, it still wont start i lifted bonnet and checked battery this is ok ,then i followed battery cable down to starter motor there i found a problem the connecter thats bolted on to the starter motor has snapped on the neck of connector could this be the problem why it wont start or is my starter motor u.s could i go to an auto electrician and get a new connector put on battery cable or starter cable or do you have to replace the whole thing hope to hear from you soon
