To make it possible to apply high extraction force as a clip for installation of floor carpet comprising female and male members.SOLUTION: A clip 1 for installation of floor carpet comprises a male member 3 having a lower flange part 30 and a shank 35, and a female member 2 having an upper flange part 25 projected on a circumference of a cylindrical part 20, causes the shank to penetrate through an insertion hole of a floor carpet 10 and causes the cylindrical part 20 to engage with a projection of the penetrated shank, whereby the clip is installed on the floor carpet in the state of sandwiching the floor carpet by the upper and lower flange parts, and can fix a floor mat or the like, that is placed on a top face of the floor carpet, by use of the cylindrical part of the female member. The male member has a pore 37 through which the lower flange part and the shank penetrate in an axial direction, and an engagement protrusion 39 projected on a circumference of the shank. This clip has a regulation member 34 which is inserted in the pore and makes the engagement protrusion to be unable of releasing engagement from engagement parts 26, 27 provided on an inner periphery of the cylindrical part in the state that the engagement protrusion is elastically engaged with the engagement parts with respect to the female member.SELECTED DRAWING: Figure 5
