<p>In a clip(1) that copes with pitches of a plurality of types of screw grooves(31V), force to support the engaged screw members(31) is increased at low cost. Each elastic locking piece(13) extends from the first side to the second side opposite to the first side, in the direction of the axis(31X) of the screw member(31) such that its leading end approaches the screw member(31) within the insertion hole(19) of a tubular body part(11). Each elastic locking piece(13) is elastically deformable such that its leading end is separated from the screw member(31). Each locking piece(13) has at its leading end a locking claw(13V) that engages with the screw groove(31V) of the screw member(31). A claw leading-edge (13v) of the locking claw(13V) has a straight section(13V1) extending straight on one side in a circumferential direction(R) around the axis(31X), and a curved section(13V2) extending curvedly along the circumferential direction(R) on the other side.</p>
