The` present invention relates generally to the binder art, and more particularly to a no vel locking device for a metal for engaging and supporting atelephone directory or the like.

The' locking `device comprises a member slidn portion I8 with semicircular-shaped upturned end ably mounted on the free end of a rod- like retainportions 20 and 22 normal thereto.
