Abstract
A line marker apparatus for visibly marking the location of a utility line and the like has a tube disposed vertically in the ground. A locking ring is disposed on the tube and has a plurality of locking fingers extending from the ring. The locking finger are bendable in towards the tube. A cap or marker is removably coupled to the locking ring. The cap has an open end for receiving the locking ring and a protrusion extending into contact with the locking finger for forcing the locking finger in towards the tube. Ribs may be formed on an inner surface of the fingers to prevent the locking ring from rotating on the tube. A slot may be formed in the locking ring or cap to vent the cap. An indentation may be formed in the cap to receive indicia.
