The invention relates to a puncture repair kit which prevents an extraction cap from getting detached in a high-temperature environment while minimizing the force for attaching the extraction cap in a low-temperature environment. A connection means (7) for connecting a compressor (3) and an extraction cap (5) comprises first and second connection parts (7A, 7B). The first connection part (7A) includes outwardly projecting hook pawl parts (28) each having a triangular cross-sectional shape and having a catching surface (28S), each hook pawl part being provided on the tip end part of each of a pair of plate-shaped base parts (27) extending from the extraction cap (5) in a connection direction and along both sides of an intake opening (10). The second connection part (7B) has engagement surfaces (29S) that engage with the catching surfaces (28S). The angle 1 of the catching surfaces (28S) is different from the angle 2 of the engagement surfaces (29S); or a plate-shaped section (40), which is a region from the rear end, in the connection direction, of the plate-shaped base part (27) to the hook pawl part (28), includes a constant-width section (40A) and a narrowed section (40B).
