That’s the same as mine Craig......the standard Ctek connectors.
Yes, that's the connector type Graham was referring to. They have a slight weak point in their design, which is that because they comprise a male/female socket pair, the female half can gradually widen with repeated connection/disconnection.
The female connector consists of a tube with a longitudinal slit, and any slight misalignment when the connection is made or broken can gradually open this slit up a bit, making the connection a bit dodgy.
Easily fixed either by giving the female connector a little tweak or by replacement, there are other connectors available which are designed for repeat connection/disconnection that avoid this potential problem by having two blades which rest against each other rather than a male/female arrangement.
So long as you are not careless about the standard connector, however, they should be good for many years of usage.
