• a grip handle for an operator's palm to which is rigidly connected said cylindrical container in such a manner that said grip handle and said cylindrical container form a pistol-like assembly;
• a coupling duct which extends inside said handle portion and which is in communication at a first end thereof with said passage of said cylindrical container, said coupling duct having a second end to which is connectable an air aspirator means;
• an aspiration hole which is in communication with said passage of said cylindrical container and which is arranged so as to be easily blocked by a user's thumb during use;
• pusher element means slidably arranged on said cylindrical container for engaging and pushing said dilated ligature element off said open end of said cylindrical container;
