Abstract: A cooling/heating panel has a planar radiation panel (12), a metallic holding member (18) arranged partially on a backside of the radiation panel (12), and a resin heat exchange pipe (16) held by the holding member (18). The holding member (18) has: a flat soaking plate (20) which is superimposed on the radiation panel (12); and a holding portion (22) which is erected on the soaking plate (20) and latches the heat exchange pipe (16). The heat exchange pipe (16) has an outside diameter larger than an inside diameter of the holding portion (22) before the heat exchange pipe (16) is attached to the holding portion (22) and in a state in which the heat exchange pipe (16) is attached to the holding portion (22), the holding portion (22) holds a side face of the heat exchange pipe (16) repulsively from both sides.

Abstract: The invention completely prevents a twist of a hose in accordance with a fastening. A loosely fitting portion (4) is rotatably fitted along an outer peripheral surface (1b) of a nipple (1), the loosely fitting portion (4) and a sleeve (2) are independently attached so as to be immovable in an axial direction, and a fastening member (3) is screwed on an outer peripheral surface of the loosely fitting portion (4) so as to be movable in the axial direction toward the sleeve (2). Accordingly, if the fastening member (3) is pulled in a fastening direction without rotating while only rotating the loosely fitting portion (4), after attaching a hose (H) along an outer peripheral surface (1a) of the nipple (1), the sleeve (2) is reduced in diameter accordingly without being exposed to a rotating force, and the hose (H) is closely attached in its inner peripheral surface (H1) to the outer peripheral surface (1a) of the nipple (1) without being exposed to an external force caused by a rotational friction at all.
