Integrally formed with a projecting claw portion 11, and the claw portion 11 engages with the engaging concave portion 8 of the terminal 6 to hold the terminal 6 in the terminal insertion portion 2 in a state in which it does not come off. . And the nail part of the arm part 10
On the side faces 10a, 10a on both sides of 11, groove portions 12, 12 as guide ridge portions extending in the front-rear direction which is the extending direction of the arm portion 10,
The arm portion 10 is formed over substantially the entire length of the arm portion 10 from the front end portion to the base end portion. Further, inside the housing 1, a spacer insertion portion 13 is formed adjacent to the lower portion of the terminal insertion portion 2 in FIG. 1 and extending from the base end of the engaging claw 9 to the front of the housing 1. An opening 13a is formed at the left end of the spacer insertion portion 13 in FIG. Further, on the inner surface of the partition walls 3, 3 of the housing 1, a regulating projection 13c which is located between the terminal insertion portion 2 and the spacer insertion portion 13 and projects inward (only one side is shown in FIG. 1). ) Are provided facing each other. This regulation projection 13
The c extends from the left end of the housing 1 in FIG. 1 to the front of the tip of the engaging claw 9.

As shown in FIG. 3, 14 is a long spacer, and as shown in FIG. 3, standing walls 16 and 16 are formed on both left and right sides of the bottom wall 15, and the upper and lower walls 16 and 16 are formed at the same time. Protruding ridges 17, 17 are formed as engaging ridges toward the inside, and the cross-sectional outer shape is a substantially rectangular shape (second
See figure). The spacer 14 is inserted into the spacer insertion portion 13 of the housing 1 through the opening 13a thereof, and by the insertion, both ridges 17 and 17 are inserted into the groove portions of the engaging claw 9 as shown in FIG. 12, 12 are fitted and engaged over substantially the entire length thereof.
