I used slider clips for years.
In my 'youth', it was discovered that the ends would loose a little tension after many uses and open up when stressed while flying.
Ringmaster Combat and the like....
By slightly bending the ends 'open' they clicked onto the slider firmly.
However, when the scissor type became available, I switched.
'Hello Kitty' clips are the ones I presently use because of the small increments of length they provide.
Great care must be used when using/installing ANY line clips.
STAY SAFE & "Tight Lines!"
