A temporary cylindrical road bollard 1 for lane marking has a fitment portion comprising an annular groove 3 and a foot 4 having a chordal portion 5 removed. The foot 4 can be manipulated past lugs 8 and 9 in a recess 6 of a road stud housing 7. The bollard is then rotated so that remaining circular portions of the foot 4 will be positioned beneath the lugs 8 and 9 to retain the bollard in position. Chordal portions 5 may be cut away on both sides for ease of insertion of the bollard past the lugs and the groove 3 may incorporate stops limiting the extent of rotation of the bollard. <IMAGE> |
