A variable width end attachment for a bracelet or the like comprises a base-plate 8, a pair of elements 10, 12 laterally slidably mounted on the base-plate for movement toward and away from one another, resilient means, a spring 14 operatively connected to the elements and urging them laterally away from one another, and a shell 16 operatively connected to the base-plate and covering the elements and the resilient means, the elements projecting laterally beyond the shell, track means 52 on the elements, and parts 78 extending from the shell slidably engaging the track means to define therewith a bearing guide for the elements. The base-plate has a section 18 with apertures for attaching the last two links of the bracelet and a stepped down section with openings 32 which register with slots 40 in the slidable elements. Eyelets engage in the openings 32 and slots 40 for sliding movement of the elements against the action of the spring 14 secured to a hook 42 on each element. The sliding elements have a narrow portion 38 with a channel section with track means 52. The track means forms a guide for depending parts 78 on a shell portion 54. The shell has a narrow portion 56 overlapping the ends of the channel sections. The portion 54 has tags 64, 66 and 68 which engage the base-plate portion 28 and the portion 56 has a tag 76 which engages the base-plate portion 30. A tag 70 on the portion 54 engages the centre of the spring. To attach the bracelet to the watch case, the elements are placed between the lugs by pressing on portion 38, a spring pin or pins being positioned in the channel members.
