In both cases, a locking portion protrudes from a wire harness mounting portion, and the locking portion is connected to a vehicle body panel. The locking wings on both sides provided in a folded shape from the tip of the locking portion are locked and fixed to the inner surface side of the mounting hole.

For example, in a substrate type clamp 1 shown in FIG. 4, a shaft portion 1c of a locking portion 1b is projected from a substrate 1a which is fixedly wound around a wire harness W / H with a tape T on both sides thereof. Blades 1d, 1db are provided in a folded shape from both sides of the tip, and stepped notches 1e, 1e are provided at the tips of the blades 1d, 1d. In order to mount the clamp 1 in the mounting hole 2a of the vehicle body panel 2, the clamp 1 is inserted into the mounting hole 2a by the tip of the shaft portion 1c of the locking portion 1b,
The blades 1d, 1d on both sides are bent to reduce the diameter, and after the blades 1d, 1d pass through the mounting hole 2a, the blades 1d, 1d
d returns to its original shape and spreads, the notches 1e and 1e at the tips are locked to the inner peripheral edge of the mounting hole 2a, and the clamp 1 is fixed to the vehicle body panel 2.
