  • the release element (32) can be movably coupled to the female coupler (4), whereby travel of the release element (32) along or over a female coupler outer surface (66) disengages the catch (14) from the catch-receiving element (15) to achieve the disconnected condition of the connector system (1).
  • linear or sliding motion of the release element (32) along the female coupler outer surface (66) can be transformed into movement of the follower (17), whereby this movement of the follower (17) can forcibly urge the catch-biasing member (16) away from the normal unflexed condition (29) and toward the flexed condition (31) to allow the catch (14) to move outwardly away from the female coupler inner space (11) or downwardly in the plane (26) to disengage from the retention groove (22).

For example, the follower (17) can be movably disposed within an opening (33) defined by the female coupler outer surface (66) (as shown in the example of Figure 9A), whereby the opening (33) can be sufficiently configured to allow movement of the follower (17) through the opening (33) and inward toward the female coupler inner space (11) or downward in the plane (26), or outward away from the female coupler inner space (11) or upward in the plane (26).
  • a release element inner surface (34), which disposes proximate (or adjacent) the female coupler outer surface (66), can provide a cam surface (35) having a locking surface (36) and an unlocking surface (37), both of which can separately interact with or directly contact the follower (17) to result in movement of the catch (14).
  • the unlocking surface (37) extends downwardly toward the female coupler outer surface
  • the locking surface (36) extends upwardly away from the female coupler outer surface (66) a greater distance than the unlocking surface (37), thereby disposing the locking surface (36) farther from the female coupler outer surface (66) than the unlocking surface (37).
  • a release element-biasing member for example a resiliently compressible member (39) can bias the release element (32) toward a release element first position (40) when in a non- compressed condition (41), which is the normal biased condition.
  • the locking surface (36) aligns with (or contacts) the follower (17) and correspondingly biases the catch (14) inwardly or upwardly and toward engagement with the retention groove (22) to achieve the connected condition of the connector system (1).
  • the resiliently compressible member (39) can be compressed toward a compressed condition (42), disposing the release element (32) in a release element second position (43) in which the unlocking surface (37) aligns with (or contacts) the follower (17), biasing the catch-biasing member (16) toward the flexed condition (31), allowing the catch (17) to move outwardly away from the retention groove (22) to achieve the disconnected condition of the connector system (1).
  • the catch (14), the catch-biasing member (16), and the follower (17) can be integrated to provide a catch-assembly (2) which (i) can be a one-piece construct or (ii) can be formed as a one-piece construct.
