摘要：
A tensioning device used for achieving mass-production interchangeability of the barrels for a shotgun with articulated barrels is positioned between the barrels and the breech of the gun and comprises a rod-shaped element constituted by a fixed portion and a movable portion guided for moving on the fixed portion and subject to the action of a powerful spring which urges it against a tenon. Means are provided for adjustably engaging the rod-shaped element on the tenon.
