PROBLEM TO BE SOLVED: To suck up objects by separably connecting aspirators workable without commercial power sources to the base end opening of tubes inserted in the insertion part of endoscopes. SOLUTION: An aspirator body 27 has on one side wall springy power contacts 41 and 42, while a battery unit 28 has on the related side wall power contacts 49 and 50 related to the power contacts 41 and 42. The aspirator body 27 has on its back end L-shaped projections 43 and 44, while the battery unit 28 has on the related side mating L-shaped projections 45 and 46. A sliding inter-fit of those L-shaped projections 43 to 46 of the aspirator body 27 and battery unit 28 releasably couples the battery unit 28 to the aspirator body 27.
