CPC:

Couplings of the quick-acting type ( radially-binding sleeves F16L17/04, F16L21/06; connecting hoses to rigid members F16L33/00) > in which the connection between abutting or axially overlapping ends is maintained by locking members (F16L37/22 - F16L37/26 take precedence) > using a rotary external sleeve or ring on one part

CPC subdivides this area 3x more granularly than IPC with 3 additional codes.

IPC defines codes here since 2000.
