Abstract
A coupling assembly including a coupler body having a generally cylindrical shape and an opening at one end. The coupler body has an inner wall with an inner circumference and an outer wall. An abutment extends from the inner wall of the coupler body. The coupling assembly further includes a conduit having a generally cylindrical shape complementary to the coupler body. A coupler key groove extends along the inner circumference of an inner wall of the coupler body and is shaped like part of a parallelogram. The conduit has a conduit key groove and is generally shaped like part of a parallelogram. When the coupler key groove and the conduit key groove are aligned they form a pathway shaped like a parallelogram with two acute angles. An aperture in the wall of the coupler provides access to the pathway for a locking strip or flexible key. The locking key has a cross-section, which is a complementary shaped parallelogram. A sealing groove is also provided along the inner wall of the coupler to hold an O-ring.
