Abstract
A pressure cylinder assembly includes a cylinder and an outwardly projecting flange. The assembly is formed by inserting into the cylinder open end a body having a groove in its outer surface, so that the groove lies in opposition to a wall of the member, and deforming said wall into the groove to lock the body axially within the member. This deformation produces corresponding depressions in the outer surface of the member. A flanged collar is then placed around the member and deformed into the depressions to lock the collar axially and rotationally relative to the body with the flange of the collar projecting outwardly for mounting the assembly on a support.

A method of forming a pressure cylinder assembly which includes a cylinder and an outwardly projecting flange, comprises the steps of inserting into a tubular member a body having a depression in its outer surface such that said depression lies in opposition to the wall of the member, deforming said wall into the depression to lock the body at least axially within the member and to form a secondary depression in the outer surface of the member, placing a flanged collar around the member and deforming the collar into the secondary depression in such a manner as to lock the collar axially and rotationally relative to the body so that a flange of the collar may then serve to mount the assembly on a support.
