ABSTRACT:
A device for retaining an attachment member having an engagement portion for engagement with an outer circumferential surface of a rod-like member, comprising: a receptacle for receiving a main part of the attachment member with some play; an elastic member for retaining the main part at its first position for keeping the rod-like member and the engagement portion from interfering with each other when the rod-like member is brought into a preliminary position for engagement with the engagement portion; and a pressure unit for bringing the attachment member to its second position for engaging the engagement portion with the rod-like member against a biasing force of the elastic member. When the attachment member is placed in the receptacle, it is held in its first position for not causing any interference between the engagement portion and the rod-like member by being supported by the elastic member. The rod-like member is then placed at a prescribed position. By pushing out the pressure unit against the action of the elastic member, the attachment member is made to assume the second position where the engagement portion is engaged with the rod-like member so that the attachment member may be retained in the receptacle.
