Abstract
Abstract A connector is disclosed for joining together rigid hollow tubular members which may move relative to each other which connector includes a casing of resilient material preferably elastomeric in nature, synthetic or natural rubber, the organic elastomers or any resilient plastic material, a preferred example being an outer casing of moulded natural or synthetic rubber with a plurality of reinforcement corrugations or ribs between straight end portions which are detachably secured to the tubular members, the corrugations or ribs having grooves on the inside of the casing adjacent thereto into which relatively rigid O-rings are locked in place thereby resisting collapse of the connector due to vacuum. The connectors can be straight or curved.
