The device includes a support for supporting the article thereon, a guide having a conically shaped surface with the large diameter end of which is adapted for abutting at one end surface of the article supported on the support, a piece for moving the elastic annular ring fitted on the conical surface along the conical surface with the diameter of the ring being enlarged and thus pushing the ring onto the article and fitting the ring into the circumferential groove of the article, and a structure for supporting the guide when the guide is not abutting at the article.
