Abstract A replaceable guide post of the type generally used as a road marker and the like, wherein a flexible tubular post member is provided with a mounting-base structure that is arranged to be secured to a ground surface such as a roadway. The base structure comprises a support-base member adapted to receive and engage a lower flanged portion of the tubular post and a retainer collar member, which is positioned over the base member and the lower portion of the guide post, thereby clamping the post therebetween and affixing the base member to the ground surface. An alternative arrangement thereof further includes a removable mounting-ring member provided with a central opening having the peripheral design of the particular tubular post to be employed therewith.
