A connection structure of a hose for transmission oil including a multilayer hose having a first rubber layer formed by a first pipe, a braided layer formed on an outer surface of the first rubber layer and formed by braiding aramid fibers. A second rubber layer located on the outer surface of the first rubber layer. A first connector including a body inserted into an inside of the first rubber layer and including a second pipe connected with the first pipe, and a stopper protruding from the body, and an inclined portion formed at an end of the body and forming an uphill slope of approximately 11°-17° to one side of the body. A second connector including a cover portion covering the multilayer hose and a plurality of pressurized portions formed concave with respect to an outer peripheral surface of the cover portion and in contact with the multilayer hose.

A piping system including a pipe and a pipe block coupled to an end of the pipe. The pipe includes: a flange positioned at the end and protruding in a radially outward direction along an outer circumference of the pipe; and a coupling portion having a nipple that is inserted into the pipe block. The pipe block includes: an insertion hole into which the pipe is coupled; and a lip protruding from a surface in which the insertion hole is formed in a circumferential direction along an outer circumference of the insertion hole. An inner diameter of the lip is equal to or greater than an outer diameter of the flange, and when the pipe is coupled to the pipe block, the flange is positioned inside the lip and the lip is deformed in a radially inward direction of the pipe to grip and fix the pipe.
