Abstract
A method of forming a connection between a tubular member and an annular collar which has at least one internal annular recess. The method includes positioning the collar over portion of the tubular member to define an axially extending connection zone embracing the annular recess, positioning a solid deformable transmitting material in the tubular member in alignment with the connection zone, confining the transmitting material axially to the connection zone, and applying a deformation force gradually to the transmitting material to deform its radially outwardly and thus deform the tubular member into the recess of the collar to form a connection.
