"e luta të mos më braktiste, iu ngjitja për këmbë" - "I begged him/her to not abandon me (or leave me), I stuck to his legs/feet". The author means that he/she is crawling to the person's legs/feet and holding them, while begging not be abandoned. That is the context of the sentence. You can also say: "I held onto his/her legs/feet" Hope this helps!
