  • tip of the smaller-diameter pipe member 2 on the side inserted into the larger-diameter pipe member 1 is expanded, for example, in a trumpet shape.
  • the expanded tip is brought into contact under pressure with the inside surface of the larger-diameter pipe member, thereby preventing the smaller-diameter pipe member 2 from coming out of the larger-diameter pipe member 1 under the own weight of the former pipe member.
  • the freely elongatable two-stage type of sucking pipe is so designed as to be shortened for convenience of storage, carriage, etc. by displacing the smaller-diameter pipe member 2 relative to the larger-diameter pipe member 1, and elongated for sucking beverage, etc. by drawing out the smaller-diameter pipe member 2 from the larger-diameter pipe member 1.
