Abstract
The present invention relates to a tubular coupling comprising a first tube having an end portion; a cage means disposed on the end portion and including a radial base portion through which the end portion projects, a first circular flange portion connected at one end thereof to the radial base portion and angularly inclined outwardly from the end portion, a curved wall portion connected to the first circular flange portion and partially forming an annular chamber, and a second circular flange portion connected to the curved wall portion and terminating in radially spaced relation to an outer surface of the end portion of the first tube. The coupling also includes a way of retaining the cage on the end portion of the first tube to hold the cage against axial displacement. A second tube having an end portion is telescopically mounted on the end portion of the first tube. The end portion of the second tube includes a ramp portion adjacent the terminal end of the second tube and is angularly disposed relative to the longitudinal axis of the second tube; and a further portion adjacent to the ramp portion which is inwardly angularly disposed toward the longitudinal axis of the second tu…
