Abstract
A modular conduit system comprises elongate conduit elements (50, 51) and conduit fitting elements (30, 37) longitudinally divided and provided with tongue and groove joints configured such that identical conduit halves or identical conduit fitting halves can be snap fitted together and released interengaged by radially directed resilient restoration forces in the fitting elements. The interengageable tongue (1a) formation and corresponding groove formation (2b) each have at least one radial curvature with the same radial origin when opposing elements are interengaged.
Claims13
A modular conduit system comprising:
- frictionally engageable longitudinally divided elements engageable to form a hollow conduit having a smooth bare of substantially circular cross section, said elements having one or more interengageable complementary tongue and groove formations along opposed free edges thereof, said tongue formation and said groove formation each having at least one radial curvature with the same radial origin located on a central axis of said bore when opposing elements are interengaged, said opposing elements being engageable or disengageable against radially directed resilient restoring forces applied between said opposing elements.
