ABSTRACT:
A mechanical pipe connector which is especially suited for interconnecting sections of large tubular piling. The connector includes a tubular inner member having a wall with a first annular groove cut in the outside face thereof, and a tubular outer member having a wall with a second annular groove cut in the inside face of the wall. At least one hole extends from the second annular groove through the wall of the outer member to the outside thereof. The inner member fits into a passage in the outer member with the first and second annular grooves juxtaposed to form a common annular channel between the inner and outer members. A flexible locking tape is inserted through the hole in the outer member and into the annular channel to lock the inner and outer members securely together. The locking tape and the annular channel each have a polygon cross-sectional shape with the polygon having obtuse angles to minimize the stress concentration on the loading tape and on the walls of the annular channel.
