- a hard body having a lower end, the lower end having an outer surface;
- a fluid inlet formed on a top face of the hard body and a fluid path formed in the body in communication with the fluid inlet;
- an outer cylinder so fixed on the body as to contain the latter, having a lower end and being open at the lower end, the lower end having an outer surface;
- first and second calking rings, the calking rings being unthreaded;
- a tube fixed to the outer surface of the lower end of the outer cylinder solely by means of the first calking ring and fixed to the outer surface of the lower end of the hard body solely by means of the second calking ring, the first and the second calking rings each being of hollow cylindrical form and of substantially rectangular axial cross section and each having an outer surface free of contact with any other surface, the first calking ring having an inner surface in contact only with a first cylindrical surface portion of the tube, a first cylindrical segment of the tube including the first cylindrical surface portion being sandwiched between the inner surface of the first calking ring and the outer surface of the lower end of the outer cylinder, the second calking ring having an inner surface in contact only with a second cylindrical surface portion of the tube, a second cylindrical segment of the tube including the second cylindrical surface portion being sandwiched between the inner surface of the second calking ring and the outer surface of the lower end of the hard body, the tube being fully open at both ends thereof being fixed to the hard body; and
- a space defined between the tube and the outer cylinder, the space communicating with the fluid path and otherwise being closed;
- whereby the tube inflates inwardly and grips an object when a fluid such as air is supplied into the space through the fluid path from the fluid inlet.
