A connector for setting a layout of a brake hose disposable between a caliper housing and a frame of a master cylinder in a vehicle, the connector comprising: a first coupling member couplable to one end of the brake hose; a second coupling member disposed to be spaced apart from the first coupling member, and coupled to the caliper housing or the frame of the master cylinder; and an adjusting unit connected at one end thereof to the first coupling member, connected at other end thereof to the second coupling member, and configured to adjust a length between a bottom surface of the first coupling member and an outer circumferential surface of the second coupling member and to adjust a line passing through a center of the first coupling member with respect to the second coupling member to be positioned in one of up/down/left/right directions, in a test for setting the layout of the brake hose, wherein the adjusting unit includes: a length adjuster including a first length adjusting bar connected at one end thereof to the second coupling member, and a first tube body slidably coupled to other end of the first length adjusting bar; and a position adjuster including a first linking portion formed at other end of the first tube body, a second tube body connected at one end thereof to the first coupling member and having a bent portion at the other end thereof, and a second linking portion formed at an end of the bent portion and combined with or separated from the first linking portion, characterized in that the first linking portion includes a plurality of first protrusions protruded from other end of the first tube body and arranged at regular interval, and a plurality of first grooves each formed between adjacent first protrusions, and in that the second linking portion includes a second linking portion body protruded from an end of the bent portion of the second tube body, a plurality of second protrusions arranged at regular intervals on an outer circumferential surface of the second linking portion body, and a plurality of second grooves each formed between adjacent second protrusions. a first coupling member couplable to one end of the brake hose;
