Abstract
A coupling for two tubes forcibly engaged one into the other, the two tubes being substantially of the same sections while the female tube is engaged into a sleeve or an opening whose diameter is little larger than the outside diameter of said tube. Thus, the female tube is crimped or banded in the sleeve or opening while the male tube is forced to contract. This assembly means may be used for making balustrades or ladders or assembling various members which are fixed with respect to the tubes or the ring.
