• a handle having a threaded end threadedly connected in said handle receiving opening;
• and,
• a locking adaptor means for preventing inadvertent unthreading of said handle from said head, said adaptor means comprising;
• a generally cylindrical collet body member formed independently of said head and said handle extends, said collet body member being axially slidable on said handle toward and away from said head and further including resilient finger portions extending axially from said body member along said handle in a direction away from said head, a nut member threadedly received on said collet body member for movement axially thereof and including a tapered surface engageable with said finger portions for driving said finger portions radially inward into gripping engagement with said handle, and engagement means extending axially between said collet body member and said head for preventing relative rotation between said collet body member and said head while permitting free axial sliding movement toward and away from said head when said nut member is unthreaded from said collet body member.
