The device has a housing with a sharpened cannula extending therefrom, and a plunger having a barbed wire extending therefrom that is slidably disposed within the housing. The barbed wire is releasable from the cannula housing by sliding the plunger, allowing the barb to engage a mass. A locking position prevents the plunger from unwanted sliding.
