This creation is a kind of piecing devices of appendix,System is made of affixed component and Quick-dismantle component,The affixed what of affixed ontology of affixed component inflates host,And plural first inserting column positions the affixed ontology of what,And Quick-dismantle component have joint body,Plural second inserting column and press element,And when not pushing the press section of joint body,The elasticity hook of press element is the affixed ontology of clip what,And first inserting column and the second inserting column pairing grafting,And when pressing what press section,It is the non-affixed ontology of clip what that elasticity, which hooks,Quick-dismantle component is set to extract outward from affixed component,Second inserting column is separated with the first inserting column； Accordingly,Except can reach group connect Hou clamping structure fastening,It is not easy except loosening,Separately hook by elasticity to hide the design inside what piecing devices,And be avoided that and appear outside what and hook the situation for pulling the bed cloth of air bed,With the convenience used in order to increasing.本創作係一種輸氣管的接頭裝置，係由固接組件及快拆組件所組成，固接組件之固接本體固接於打氣主機，而複數第一插柱定位於固接本體，而快拆組件具有接頭本體、複數第二插柱及按壓元件，且未下壓接頭本體之按壓部時，按壓元件之彈性勾係卡掣於固接本體，且第一插柱與第二插柱對合插接，而按壓於按壓部時，彈性勾即未卡掣於固接本體，使快拆組件能自固接組件向外拔出，第二插柱即與第一插柱分離；據此，除可達到組接後卡掣結構緊固、不易鬆脫之外，另藉由彈性勾為隱藏於接頭裝置內部的設計，而能避免顯露於外而勾扯到氣墊床之床布的情形，以俾增使用的方便性。
