<p>Male couplers (40; 140; 240) and female couplers (20; 120; 220) which are complementally formed to attach together are fitted with a retainer system (10; 110; 210) including prongs (39) on one of the couplers and a gap on the other of the couplers which can engage the prongs. The prong (39) or gap is configured as either fixed or pivoting so that the pivoting portion can pivot to engage the fixed portion. When the male coupler (40; 140 240) is inserted into the female coupler (20; 120; 220), the prongs (39) and gaps engage each other. To remove the male coupler (40; 140; 240) from the female coupler (20; 120; 220), a pivoting portion must be pivoted to move the gap and prongs (39) away from each other. The gap is configured as an at least partial recess into which the prong (39) is received. The prongs (39) and loop (64) or slit (130; 230) are coupled to the male and female coupler ends through removably attachable male and female retainers (30; 50) or built directly into the female and male couplers (20, 40; 120, 140; 220, 240).
