ABSTRACT:
A flexible ring device, such as a key ring for example, is formed of a section of flexible material, such as metal cable or plastic anchored at one end to a coupling sleeve. The free end of the flexible section carries a coupling plug which can be inserted axially to an open end of the coupling sleeve. The coupling sleeve is formed with a locking notch, preferably a through opening, facing radially inwardly with respect to the closed ring. When the coupling plug is inserted into the open end of the coupling sleeve, and past the locking notch, a locking portion, formed by the back end of the coupling plug, is resiliently displaced into locking engagement with a shoulder formed by the locking notch. The device is thus locked in a closed configuration against being opened by tension forces. The device can be easily opened by manually re-aligning the coupling plug with the axis of the coupling sleeve and withdrawing the plug axially from the open end of the sleeve.
