Hello Gus and Bob,
Bob, I also use "stick it" the products from these guys work well. all their products have strange names but they work well and are priced right. I think their product are just mail order and we order by the case at work.
Gus, You can always depend on 3M products for good quality but they are pricey. When glueing plastics and most synthetics you must use a an adhesive which will resist the vapors leaching out of these products. If you do not these vapors (plasticizors) will attack the adhesive and it will fail. If the product does not specifically say that it can be used on plastics then it is probably not what you need.
3M 90 (spray adhesive), is formulated to adhere plastics. 3M 70 (spray adhesive) should not be used on plastics. You should be able to find both of these at Lowes or Home Depot. Look for a black airesol can.
I believe "Stick It" is also formulated for plastics and is about half the price of the 3M but harder to find.
Yes Bob is correct, the pin is part of a sprig clip which snaps around the cable end and pins the cable (no tools required).
