first and second ends of seal member 18 a and upon rotation push outward on seal member 18 a locking member 16 b engages the first end 21 a and second end 21 b of seal member 18 a such that by turning locking member 16 b clockwise pressure is applied to first end 21 a and second end 21 b of seal member 18 a at links thereby extending seal member 18 a into receiving portion 18 b once engaged male component 10 a and female component 10 b are sealably and fixedly engaged such a mechanism can withstand tremendous pressure since the forces acting in the pipe are transverse to the locking member 16 b and its engagement to seal member 18 a to disengage male component 10 a and female component 10 b locking member 16 b is rotated in the opposite direction from its first position to relax pressure on first end 21 a and second end 21 b of seal member 18 a and then a cylindrical mechanism not shown can be inserted into retractable tabs 20 b which in turn acts to drive individual seal members 18 a into a collapsed or relaxed position such that male component 10 a can be removed from female component 10 b once all jointed subsections 19 are disengaged from receiving channel 18 b male component 10.
