Flexible Air Hose Coupling Lock for Mixed-Size Connections

The coupling system is divided into distinct male and female coupling components with specific geometric features. The male coupling includes an outwardly directed flange and the female coupling includes a corresponding recess, creating segmented interfaces that guide proper alignment and prevent inadvertent disconnection while maintaining ease of connection.

The male coupling is designed to be inserted into and nested within the female coupling. The male coupling's flange fits into the female coupling's recess, creating a nested configuration that secures the connection through geometric interlocking while allowing straightforward assembly.

Security features are applied locally at specific interfaces rather than throughout the entire coupling structure. The outwardly directed flange on the male coupling and the corresponding recess on the female coupling provide localized geometric interlocking that enhances connection security without adding complexity to the overall coupling design.

Instead of using complex locking mechanisms that require active engagement, the design uses passive geometric features where the male coupling's flange naturally interfaces with the female coupling's recess. This inverted approach provides security through the absence of complex active components rather than their presence.

The securing apparatus is designed with a universal configuration that can accommodate multiple coupling sizes and styles. The male and female coupling design with standardized flange and recess interfaces allows the same basic structure to work across different applications, achieving multi-functionality without requiring precision customization for each size variant.

The design allows for parameter variations in coupling size and dimensions while maintaining the fundamental geometric interface structure. By changing dimensional parameters rather than the fundamental design approach, the system achieves adaptability to various sizes while maintaining consistent manufacturing tolerances for the core interfacing features.
