A connection assembly has a body (10,10A), a connecting end (20,20A) and a sealing base (30,30A). The body (10,10A) is hollow and has a connection base (15,15A) having a front face and two engaging channels (152,152A) defined in the front face and facing to each other. The connecting end (20,20A) with a suction tube is detachably attached to the connection base (15,15A) and has a connection plate (22,22A) held slidably in the engaging channels (152,152A) in the connection base (15,15A). The sealing base (30,30A) is mounted detachably on the connection portion (14) and has a sealing face (32,32A) and a guiding channel (34,34A). The sealing face (32,32A) is flush with the front face of the connection base (15,15A). The guiding channel (34,34A) is defined around the sealing face (32,32A) and communicates with the engaging channels (152,152A) in the connection base (15,15A).
