ABSTRACT:
A security lock apparatus for engagement with and locking on a break line coupler of the type having a housing with a central seal, a tongue projecting laterally in one direction and a crown mounted on the opposite side thereof and formed with a turned back cap defining a downwardly opening groove. A lock body is formed with an under surface defining a seat for overlying the seal and having a downwardly depending flange formed on one side thereof with a turned back rim defining an opened ended track for receipt of such tongue. Projecting from the opposite side of such body is a rail formed with an upturned arcuate rib for sliding receipt in the groove. The rail, rim and seat are configured and arranged such that the body may be positioned with the seat overlying the seal and in a rotational position relative to the coupler so that such rail and rim are clear of the respective cap and tongue and to then allow for rotation of the body relative to the coupler to orbit such rail and rim into engagement under the respective cap and tongue to be held securely in position. A lock is mounted in the body and is operable to extend a plunger therefrom to engage one end of the tongue to limit relative rotation between the body and coupler to thereby maintain the body in its locked position.
