Safety catch connector

A safety catch connector, comprising:

• an elongated catch member comprising an elongated retention arm providing a hanging space and a notch which forms at said hanging space, a first sleeve formed at one end of said retention arm, and a second sleeve at an opposed end of said retention arm to define said notch between said first sleeve and said second sleeve, wherein said first sleeve has a first sleeve hole formed at an axial direction and a locking groove which is radially formed at a bottom side of said first sleeve, wherein said second sleeve has a second sleeve hole formed at an axial direction to coaxially align with said first sleeve hole of said first sleeve;
• an elongated locking shaft having a first end slidably passing through said first sleeve hole of said first sleeve and a second end slidably inserting into said second sleeve hole of said second sleeve to close said notch, wherein said locking shaft further has a first engaging slot radially formed at said first end of said locking shaft to align with said first sleeve and a manipulating portion extended from said first end, wherein a controlling channel is formed at an end of said manipulating portion at an axial direction thereof, wherein a shaft locking hole is radially formed at said locking shaft between said first end and said second end to communicate with said controlling channel and is positioned close to said first sleeve when said locking shaft is coupled between said first sleeve and said second sleeve at a closed position to close said notch;
• a first controlling unit comprising a first locking element slidably coupled at said locking groove to slidably disposed at said first sleeve hole, wherein said first locking element has a locking channel formed therewithin, wherein said first controlling unit further comprises a first resilient element biasing against said first locking element to ensure a top edge of the locking channel being engaged with said first engaging slot of said locking shaft to lock up said locking shaft;
• and
• a second controlling unit comprising an elongated controlling latch slidably coupled at said controlling channel, a second locking element disposed at an opening end of said shaft locking hole to slidably bias against an outer circumferential surface of said controlling latch, and a second resilient element disposed in said controlling channel to ensure said second locking element to be biased against an inner wall of said first sleeve hole of said first sleeve, wherein in order to open up said notch, said first locking element and said controlling latch are pressed at the same time to unlock with said locking channel and said second locking element respectively, so as to allow a sliding movement of said locking shaft.
