Abstract
There are disclosed several embodiments of a connector for connecting tubular members in end-to-end relation wherein a ring supported by the one tubular member carries arcuate latches which are adapted to be moved by radial actuators into and out of positions in which locking shoulders thereon are tightly engaged with a complementary locking shoulder about the other tubular member to hold the members in end-to-end relation.
Claims9
A connector comprising
- first and second tubular members disposable in end-to-end relation,
- said first member having a locking shoulder facing away from its end,
- a ring supported on said second member and having an inner side surrounding the first member when said first member is disposed in end-to-end relation with the second member, and
- arcuate latches each having a locking shoulder and carried about the inner side of the ring for guided movement between outer positions to permit the ring to be moved over the first member and inner positions in which their locking shoulders are tightly engaged with the locking shoulder of the first member so as to hold the members in end-to-end relation,
- actuators each connected to a latch intermediate its end and mounted on the ring for moving the latches between their inner and outer positions, and
- pushers mounted on the ring on opposite sides of each actuator for inward movement, following movement of the latches into their inner positions, to engage and move the ends of the locking shoulders of the latches more tightly against the locking shoulder of the first member.
