摘要
A plug (1, 301) for plugging a line (101), the plug comprising: a seal (2); a first end assembly (10, 310) located at a first end (4) of the seal (2) and a second end assembly (40) located at an opposite second end (5) of the seal (2), the first end assembly (10, 310) comprising at least one gripping member (16, 17, 316, 317) that is configured to grip an inner surface of the line (101); and an actuator (50) configured to draw the first (10, 310) and second end (40) assemblies together when there is a relative motion between the actuator (50) and the first end assembly (10, 310), characterised in that: the actuator (50) is configured to actuate the gripping member (16, 17, 316, 317), and the plug (1, 301) is arranged such that: an initial part of a motion of the actuator 50 actuates the gripping member (16, 17, 316, 317) to grip the inner surface of the line (101), thus inhibiting motion of the first end assembly (10, 310), and a subsequent part of the motion of the actuator (50), relative to the thus motion-inhibited first end assembly (10, 310), draws the second end assembly (40) toward the first end assembly (10, 310) so as to compress the seal (2) such that the seal (2) may seal against the inner surface of the line (101) thus plugging the line (101).
