Claim:
A modular system for coupling water filter manifold heads, the system comprising: a first and second manifold head ( 96 , 104 ), each manifold head having a first side and a manifold head cavity, the first side including a pair of ramps ( 138 , 140 ), each ramp having a first end and a second end, with a ramp edge ( 144 , 146 ) defined between the first end and second end, the pair of ramps arranged in an opposed and outwardly facing relationship, with the first ends adjacent the first side and the second ends extending away from the first side inward within the manifold head cavity, the first ends of the pair of ramps ( 138 , 140 ) defining a distance D 1 , and the second ends of the pair of ramps ( 138 , 140 ) defining a distance D 3 , wherein the distance D 3 is greater than the distance D 1 , the pair of ramps ( 138 , 140 ) each defining, at the second end, a locking edge extending in a direction which diverge; and a clip ( 110 ) having a body ( 114 ), a first pair of arms ( 112 ) extending from the body ( 114 ) in a generally first direction, and a second pair of arms ( 112 ) extending from the body ( 114 ) in a generally opposite direction, each pair of arms ( 112 ) having a latch ( 117 ) at a distal end, each pair of latches ( 117 ) define a distance D 2 , wherein D 1 is less than or equal to D 2 which is less than or equal to D 3 .
