A cup device for supporting a headed lifting stud in a concrete product, wherein the cup device comprises a cup member configured to be cast into the concrete product so that an inner surface of an open top space of the cup member forms a part of an outer surface of the concrete product and so that a headed lifting stud to be cast into the concrete product projects through an opening in the cup member from concrete of the concrete product into the open top space of the cup member, and a detachably attachable support member configured to keep the headed lifting stud in position with respect to the inner surface of the open top space of the cup member, wherein the detachably attachable support member is detachably attachable to the cup member by means of first connection means and detachably attachable to the headed lifting stud by means of second connection means, wherein the detachably attachable support member covers the open top space of the cup member only partly, wherein the second connection means comprise a plurality of first deflectable leg means defining a first blind tubular inner space therebetween, wherein at least some of the first deflectable leg means have a first projection at the end of the first deflectable leg means projecting into the first blind tubular inner space, and wherein the first blind tubular inner space has a first abutment surface forming a bottom of the first blind tubular inner space, wherein the first blind tubular space is configured to receive a head of a headed lifting stud so that said plurality of first deflectable leg means press against a circumferential outer surface of the head of a headed lifting stud while the head of a headed lifting stud is pressed between the first abutment surface and the first projections projecting from the first deflectable leg means, wherein said plurality of first deflectable leg means extend from a central portion of the detachably attachable support member, characterized in that: said central portion of the detachably attachable support member is circular; two fastening portions extend diametrically from the central circular portion, each fastening portion being provided with a snap retainer of the first connection means for detachably attaching the detachably attachable support member to a circumferential edge of the cup member; and the detachably attachable support member covers the open top space of the cup member only partly by forming at least one sight opening between the circumferential edge of the cup member and the detachably attachable support member. a cup member configured to be cast into the concrete product so that an inner surface of an open top space of the cup member forms a part of an outer surface of the concrete product and so that a headed lifting stud to be cast into the concrete product projects through an opening in the cup member from concrete of the concrete product into the open top space of the cup member, and a detachably attachable support member configured to keep the headed lifting stud in position with respect to the inner surface of the open top space of the cup member, wherein the detachably attachable support member is detachably attachable to the cup member by means of first connection means and detachably attachable to the headed lifting stud by means of second connection means, wherein the detachably attachable support member covers the open top space of the cup member only partly, wherein the second connection means comprise a plurality of first deflectable leg means defining a first blind tubular inner space therebetween, wherein at least some of the first deflectable leg means have a first projection at the end of the first deflectable leg means projecting into the first blind tubular inner space, and wherein the first blind tubular inner space has a first abutment surface forming a bottom of the first blind tubular inner space, wherein the first blind tubular space is configured to receive a head of a headed lifting stud so that said plurality of first deflectable leg means press against a circumferential outer surface of the head of a headed lifting stud while the head of a headed lifting stud is pressed between the first abutment surface and the first projections projecting from the first deflectable leg means, wherein said plurality of first deflectable leg means extend from a central portion of the detachably attachable support member, characterized in that: said central portion of the detachably attachable support member is circular;
