• F16L 37/02 in which the connection is maintained only by friction of the parts being joined
• F16L 37/08 in which the connection between abutting or axially-overlapping ends is maintained by locking members
• F16L 37/22 in which the connection is maintained by means of balls, rollers, or helical springs under radial pressure between the parts
• F16L 37/24 in which the connection is made by inserting one member axially into the other and rotating it to a limited extent, e.g. with bayonet-action
• F16L 37/26 in which the connection is made by transversely moving the parts together, with or without their subsequent rotation
• F16L 37/28 with fluid cut-off means
• F16L 37/48 for fastening a pipe on the end of a tap
• F16L 37/5 adjustable; allowing movement of the parts joined
• F16L 37/56 for double-walled or multi-channel pipes
• F16L 37/58 the extremities of the two halves of the joint being pressed against each other without being locked in position
• F16L 37/6 with plug and fixed wall housing
• F16L 37/62 pneumatically or hydraulically actuated
