A fastener-installing tool comprises a housing in which a collet which holds a fastener moves back and forth between a forward fastener-installing position and a rear loading position. A curved feed tube is pivoted on the housing to swing about its center of curvature into a fastener delivering position in front of the retracted collet to feed into it a fresh fastener delivered through a hose from a supply. The feed tube swings out of the path of the collet when it next advances.
