Claim:
1. A subsea arrangement comprising: a first subsea structure; a second subsea structure; and a clamp connector for connecting and securing an end of a tubular member that is fixed to the first subsea structure to an abutting end of another tubular member that is fixed to the second subsea structure, the clamp connector comprising a first side facing the first subsea structure, a second side opposite to the first side and facing the second subsea structure, a first clamping element comprising a hinged first end and an opposite second end, a second clamping element comprising a hinged first end and an opposite second end, and an operating shaft connected to the first and the second clamping elements, wherein the operating shaft is moveable by an actuating tool in order to move the second ends of the clamping elements towards each other and thereby pivot the clamping elements into engagement with the ends of the tubular members; the first subsea structure comprising at least one first coupling member configured to mate with at least one first corresponding coupling member on the first side of the clamp connector, wherein the clamp connector is configured to be releasably connected and secured to the first subsea structure through the at least one first coupling member and the at least one first corresponding coupling member; and the second subsea structure comprising at least one second coupling member configured to mate with at least one second corresponding coupling member on the second side of the clamp connector, wherein the clamp connector is configured to be releasably connected and secured to the second subsea structure through the at least one second coupling member and the at least one second corresponding coupling member; wherein each of the at least one first coupling member on the first subsea structure comprises a locking member configured to engage with a corresponding locking member on the at least one first corresponding coupling member to releasably retain the at least one first coupling member and the at least one first corresponding coupling member in engagement with each other, wherein the locking member is configured to be rotated between locking and unlocking positions; and wherein each of the at least one second coupling member on the second subsea structure comprises a locking member configured to engage with a corresponding locking member on the at least one second corresponding coupling member to releasably retain the at least one second coupling member and the at least one second corresponding coupling member in engagement with each other, wherein the locking member is configured to be rotated between locking and unlocking positions.
