Claim Text:
1. A closure for containing fluid leaking from a ruptured pipe comprising: first and second housing members connected by a hinge and suitable for placing on a surface of a pipe to define an enclosed cavity between the first and second housing members and the surface of the pipe; and a clasp comprising a clasp arm and a linkage; wherein the clasp arm is coupled to the second housing member by the linkage; wherein the linkage is pivotally connected at a first end to the second housing member and at a second end to a pivot point on the clasp arm; wherein the clasp arm comprises a lever extending in a first direction away from the pivot point and a clasp latch integrally formed with the lever and extending in a second direction away from the pivot point substantially opposite to the first direction; wherein the clasp latch of the clasp arm engages with clasp arm retaining lips on the first housing member to hold the first and second housing members in a fully closed position; wherein in the fully closed position the linkage extends from the second housing member away from the clasp arm retaining lips, and the closure is in a sealed engagement with the pipe to produce a sealed joint therebetween; wherein the clasp latch of the clasp arm engages with the clasp arm retaining lips on the first housing member to hold the closure in an initial partially closed position; and wherein in the initial partially closed position the linkage extends from the second housing member towards the clasp arm retaining lips such that the clasp arm prevents the first housing member and the second housing member from opening and allows the first housing member and the second housing member to be moved along a length of the pipe.
