PURPOSE: A connection apparatus is provided to connect multi-channel duct assemblies in a tight and rapid manner by inserting and connecting the inner duct and outer duct at a time. CONSTITUTION: A connection apparatus(1) comprises an inner connection pipe section(10) and an outer connection pipe section(20). The inner connection pipe section is shaped as a cylinder, and has center pins(11) protruded from both sides of the inner connection pipe section. The inner connection pipe section has internal insertion holes(12) formed at the inner surface of the inner connection pipe section, such that inner ducts(2a) of a multi-channel duct assembly(2) are inserted into the internal insertion holes. The outer connection pipe section has outer insertion spaces(21) formed at the inner surface of the outer connection pipe section, such that outer ducts(2b) of the multi-channel duct assembly are inserted into the outer insertion spaces. Thus, the inner ducts and outer ducts of the multi-channel duct assembly are inserted and connected with each other at a time.
