Abstract
There is disclosed herein a tubular coupling comprising a first tube, a cage disposed on an end portion of the first tube, a bead for retaining the cage on the end portion of the first tube and a second tube telescopically engageable with the first tube. The coupling further include a spring disposed around the cage for preventing telescopic disengagement of the second tube from the first tube as well as a plurality of o-rings disposed on the end of the first tube. One of the o-rings is disposed at the pivot point of the coupling, the pivot point being defined as the midpoint of the distance between a first contact point and a second contact point between the first tube and the second tube when the tubes are engaged.
