[PROBLEM] To provide a pipe-connecting clamp that has a simplified structure and enables adequate detection of leakage in a flange connection part. [SOLUTION] Provided is a clamp (A1) for connecting pipes that each have a flange (92) on an end part thereof, said clamp comprising a pair of clamp bodies (1) that: extend in a semi-circular arc shape; each have on the inner-peripheral side thereof a recessed groove (11) to which a pair of flanges (92) can be fitted; and can be assembled so as to form a ring. Each clamp body (1) comprises a through-hole (13) that passes from the outer-peripheral side of said body to the recessed groove (11). The through-hole (13) is in the form of an elongated hole having a first dimension (L1) greater than a second dimension (L2), the first dimension (L1) being the length along the direction perpendicular to the axial direction of the clamp body (1) viewed in the radial direction of the clamp body (1), and the second dimension (L2) being the length in the axial direction of the clamp body (1).
