To provide a connector which connects beams of adjacent fence sections to a support and to each other, even when the beams are elongated in different directions in a plan view and inclined with different gradients.

This connector 2a is provided with: a first member 4 which is connected to an end of a first upper beam 106a and mounted on the support 102a in such a manner that an angle is adjusted around a first axis orthogonal to both the axial direction of the first upper beam 106a and that of the support 102a; a first connecting member 6 which is supported by the first member 4 in such a manner as to be rotatable on a second axis corresponding to the axial center of the first upper beam 106a connected to the first member 4; and a second member 8 which is connected to an end of a second upper beam 106b and connected to the first connecting member 6 in such a manner as to be rotatable on a third axis orthogonal to the second axis.
