Clarke's strict tangent cone Tfi (a) at a e X to a closed subset of a Banach space E is shown to contain the limit inferior of tangent cones Tx(x) to X at iasi->u,iel Several characterizations of Tfi (a) are presented. As a conse- quence various tangential and subtangential conditions for continuous vector fields on X are shown to be equivalent.
