There are 2 types of connecting pins :
- Pin with a polyamide cover : after some natural wearing off, a corresponding shape of the cover at the location of the fastener loops, will prevent the sliding.
- Non coated connecting pin : both extremities can be crushed ;
Generally, when both belt sides are under tension, the sliding off is stopped.
For the rivet fasteners and the MS fasteners, connecting pins with ring and embout goupille are available.
