Abstract
An explosive powder charge operated tool for driving fastening elements into a receiving material has a locking member supported in the housing for effecting the return movement of the driving member located within the barrel. The locking member has a radially inwardly directed nose located in the path of an annular shoulder on the driving member. A retaining member with a support shoulder holds the locking member in position within the housing. The retaining member and shoulder are rotatable about the housing for aligning an aperture in the shoulder with the locking member so that the locking member can be removed without the use of any auxiliary tools.
