A coupling device which can be used as a clasp to connect the ends of chains, bracelets, necklaces or other articles of jewelry has a male component including a shank which can be inserted into the passage of a tubular or disc-shaped female component whereby the shoulders at the rear side of the front end portion of the shank engage adjacent shoulders of the female component to prevent unintentional extraction of the shank. The shank or the female component has one or more resilient sections which can be engaged and deformed by one or more stressing portions of the other component in response to rotation of at least one component relative to the other component to thus ensure that the size of the passage is temporarily increased or the dimensions of the front end portion of the shank are reduced in order to permit extraction of the shank from the female component.
