loose keyboard/trackpad connector on motherboard

Recently my keyboard and trackpad stopped working, and I traced the problem to the connector between the keyboard and trackpad and the motherboard. I opened my Macbook Pro and detached and re-attached the connector to the socket. This got my keyboard and trackpad working again. But then a few days later, the same problem occurred, and the same fix worked. What I need for a long term solution is to firmly tape the connector against the mother, but the tape that currently covers the connector has grown a bit weak. What kind of tape do I need to buy, and where can I get it? I suspect that it's a special heat-resistant kind of cellophane tape.
