Claims

[Claims for Utility Model Registration] 1. A pair of ferrules each containing an optical fiber along its axis, a split sleeve for inserting and holding the ferrule so that the end surfaces of the optical fibers face each other, and a split sleeve that accommodates the sleeve. The optical connector has a housing that holds the ferrule and positions and fixes the ferrule at a predetermined position in the circumferential direction. An optical connector characterized by integrally forming a key portion extending in the axial direction on the circumferential surface and capable of engaging with a crack opening formed in the sleeve. (2) The housing consists of a pair of male and female housings that are arranged opposite to each other, and the key portion is provided on the inner peripheral surface of the sleeve receiving hole formed in the male housing, and one end side of the key portion is A utility model in which a key groove is formed to protrude toward the female housing, and a key groove is provided on the inner circumferential surface of the sleeve receiving hole formed in the female housing for fitting and engaging the protruding key portion of the male housing. An optical connector according to registered claim 1.
