Abstract: A tube coupling has a coupling body with a throughway open at one end to receive an end portion of a tube. A seal encircles the throughway to seal with the periphery and end of the tube and a cap is mounted on the body having a tube locking device rotatably mounted in the cap to engage and hold the tube in the cap. The cap and body have interengaging means which guide the cap on the body in an axial direction along the body with rotation of the cap from a first position in which a tube can be inserted through the cap and into the seal in the throughway and retained by the locking device and a second position advanced along the coupling body from said one end in which the tube end is held positively in engagement with the seal in the throughway. The locking device engages via a ring with the coupling body to resist rotation of the locking device with respect to the body whereby rotation of the cap between said the first and second positions does not cause the tube to rotate.

Abstract: A coupling connects a first member and a second member. The first member has a first interlocking member extending radially outward from an outer circumferential surface of an axial end. The second member includes a second interlocking member extending radially inward from an inner circumferential surface of an axial end. The axial end of the first member is inserted into the axial end of the second member, such that the first interlocking member is inserted past the second interlocking member. The first and second members are then rotated relative to one another to a locked angular orientation, in which the first interlocking member is interlocked with the second interlocking member to prevent relative axial movement of the first and second members. A key is then inserted into a keyway in the first and second members to lock the angular orientation, thereby coupling the first and second members to one another.
