A telescoping slip-together tubing joinder wherein a first and a second tube slide together, the second sliding over the first. A guide sleeve is mounted to the first tube and projects beyond it to receive and guide the second tube into the telescoping engagement. The guide sleeve is held to the first tube by a retainer which can be attached and removed by external manipulations.

A telescoping slip-together tubing joinder comprising: a first tube and a second tube each having an axis, each tube comprising an annular wall defined by a respective inside and outside circularly-sectioned concentric surface, each said tube terminating at a joinder end; the diameters of the outside surface of the first tube and the inside surface of the second tube being such that at least a portion of said tubes adjacent to said joinder ends can telescopically overlap one another; flexible seal means carried by and extending laterally beyond one of said two last named surfaces by a distance sufficient to make a peripheral seal between them when the said surfaces are sufficiently axially overlapped and being sufficiently deformable as to enable said sufficient axial overlap to occur; a guide sleeve having an inside cavity defined by a continuous, fully peripheral and unitary guide wall; and a removable retainer means engageable between said guide sleeve and said first tube to hold said guide sleeve to first tube with said guide wall projecting beyond said joinder end of said first tube, and preventing substantial axial movement of said guide sleeve when engaging the said guide sleeve to said first tube, the lateral dimensions of said guide wall, and of said outside surfaces of said first tube and said inside surface of said second tube at their joinder ends being so proportioned that, with the outside surface of second tube bearing against said guide wall, the interference circle of the first tube lies inside the interference circle of the second tube, whereby an axially telescoping thrust on the two tubes will result in the joinder end of the second tube passing axially over the joinder end of the first tube regardless of any permissible lateral offset of the axes of the tubes.
