ABSTRACT:
A disconnectable tube-to-tube coupling that includes a locking collar arred to span two radially-projecting rings carried by end fittings on the tubes. A special cam-like depresser sleeve is slidably arranged on the collar to move one of the rings into a groove in its end fitting, thereby breaking the coupling connection. The sleeve is operated by mechanical or manual force applied in the axial direction.
