Rohrkupplung

The present invention relates to a tubular coupling comprising a first tube (12) having an end portion (14); a cage means (16) disposed on the end portion (14) and including a radial base portion (18) through which the end portion (14) projects, a first circular flange portion (20) connected at one end thereof to the radial base portion (18) and angularly inclined outwardly from the end portion (14), a curved wall portion (22) connected to the first circular flange portion and partially forming an annular chamber, and a second circular flange portion (24) connected to the curved wall portion (22) and terminating in radially spaced relation to an outer surface of the end portion of the first tube (12). A second tube (28) having an end portion (36) is telescopically mounted on the end portion (14) of the first tube (12). The end portion (30) of the second tube (28) includes a ramp portion (38) adjacent the terminal end of the second tube (28) and is angularly disposed relative to the longitudinal axis of the second tube (28); and a further portion (40) adjacent to the ramp portion (38) which is inwardly angularly disposed toward the longitudinal axis of the second tube. The end portion (36) of the second tube (28) partially projects into the space between the surface of the end portion (14) of the first tube and the cage means (16).
