The disclosure relates to a coupling for a tube comprising a coupling body having a throughway open at one end to receive an end portion of a tube, a sealing ring or rings mounted in the coupling body at a location spaced from said open end thereof to engage and seal with the outer periphery of the tube, and a tube latching device for locking a tube in the coupling body. The latching device comprises a first latch within the coupling body to engage automatically with a feature on the tube when the tube end portion has been inserted sufficiently into the throughway to engage with the seals to retain the tube end portion in the coupling body and a second manually operable latch disposed externally of the coupling body engageable with a feature on the tube when the end portion of the tube has been inserted into the coupling body sufficient for the first latch to engage to provide a secondary retention for the tube in the coupling body.
A coupling for a tube or the like comprising a coupling body having a throughway open at one end to receive an end portion of a tube, sealing means mounted in the coupling body at a location spaced from said open end thereof to engage and seal with the outer periphery of the tube, and a tube latching device comprising first latching means disposed within the coupling body having at least one latch to engage automatically with a feature on the tube when the tube end portion has been inserted sufficiently into the throughway to engage with the sealing means to retain the tube end portion in the coupling body and second manually operable latching means disposed externally of the coupling body having a latch engageable with a feature on the tube when the end portion of the tube has been inserted into the coupling body sufficient for the first latch to engage to provide a secondary retention for the tube in the coupling body.
