1. A fluid device coupler for coupling a connecting portion of opposed fluid devices, the fluid device coupler comprising:
a coupling base having a depressed part with at least a part thereof curved in an arc shape, a first end edge side and a second end edge side that are continuous with an inner surface of the depressed part, and an opening portion formed between the first end edge side and the second end edge side to allow insertion of the connecting portion of the fluid devices,
a blockage member protrudable in a circumferential direction from the first end edge side toward the second end edge side and retractable in a circumferential direction from the second end edge side toward the first end edge side, and
a sliding structure configured to slidably move the blockage member toward the second end edge side of the coupling base without changing a distance radially from the coupling base.
