The fastener can be coupled with a holding device that can allow a user to selectively attach or detach a keychain or other items. Various options for constructing embodiments of the apparatus are disclosed.

1 . A fastening device for a keychain comprising:
 a holding interface configured to selectively retain and release the keychain;   a base with a front side and a back side;   a clamp attached to the back side of the base;   a connection system coupling the holding interface to the clamp; and   an ornamental plate secured to the front side of the base.   
   
   
       2 . The device of  claim 1 , wherein the clamp is configured to apply pressure to the back side of the base. 
   
   
       3 . The device of  claim 1 , wherein the ornamental plate is detachable from the front side of the base. 
   
   
       4 . The device of  claim 1 , wherein the holding interface comprises a gate. 
   
   
       5 . The device of  claim 1 , wherein the holding interface comprises a carabineer. 
   
   
       6 . The device of  claim 1 , wherein the connection system comprises at least one link. 
   
   
       7 . The device of  claim 6 , wherein the at least one link permits the holding interface to move relative to the clamp. 
   
   
       8 . The device of  claim 1 , wherein the connection system comprises a retractable zip line. 
   
   
       9 . The device of  claim 1 , wherein the plate is configured to be removable from the base. 
   
   
       10 . The device of  claim 1 , wherein the clamp is configured to selectively engage and disengage a purse. 
   
   
       11 . A system for retaining a keychain comprising:
 a container having a lip;   a fastener portion configured to fasten to the lip of the container, the fastener portion comprising an outer base and an inner clamp, the base configured to display a decorative attachment outwardly from the container, and the clamp configured to contact an inner surface of the container;   a holding interface attached to the clamp and configured to hold a keychain; and   a connection system joining the clamp to the holding interface.   
   
   
       12 . The system of  claim 11 , wherein the base has a front surface and a back surface, wherein the front surface of the base is attached to the decorative attachment and the back surface of the base is configured to contact an outside surface of the container. 
   
   
       13 . The system of  claim 11 , wherein the container is a purse. 
   
   
       14 . The device of  claim 11 , wherein the fastener is configured to disengage an edge of the container. 
   
   
       15 . The device of  claim 11 , wherein the holding interface is configured to retain one or more keys. 
   
   
       16 . The device of  claim 11 , wherein the connection system permits the holding interface to move relative to the fastener portion. 
   
   
       17 . The system of  claim 11 , wherein the container is a pocket.
