A front entry meter locking ring assembly for locking electric meters. A circular split locking ring has a U-shaped cross-section and two downturned parallel legs of equal length. A take-up fastener engages and draws the downturned legs towards each other. A lock receptacle having a hollow cylindrical portion is affixed to the interior of one downturned leg. A removable protective housing is fitted over the downturned legs and has a front aperture in axial alignment with the front opening of the lock receptacle. An unlocked conventional barrel lock is inserted into the front aperture of the housing. Then the barrel lock is locked. This radially extends the locking balls of the barrel lock into secure engagement with the lock receptacle. An elongated sealing tab is fixed within the housing by the take-up fastener. The sealing tab extends down through a narrow slot in the bottom of the housing where the tab is engaged by a tell-tale seal.
