Abstract
An apparatus for connecting a plurality of structures, such as ends of a sealing ring, with each end defining an aperture therein and with the ring being adapted to mount a meter to a meter box structure. The apparatus comprises a locking pin with a distal end adapted to be insertable through each of the apertures of the first and second ends of the ring. The locking pin comprises a head member having at least an engageable end and a fracturable member. The locking pin further comprises a shaft portion having the distal end. The apparatus further comprises a lock housing adapted to retain at least a part of the shaft portion such that the first and second ends of the ring are connected between the head member of the locking pin and the lock housing. The head member has an outer surface adapted to receive at least two opposing forces, the at least two opposing forces being of sufficient magnitude to break the fracturable member. A lock removal tool is adapted to receive and fracture a portion of the locking pin, enabling removal of the lock assembly from the meter box sealing ring.
